A new study on cell therapy for cerebral palsy has, for the first time, directly compared the efficacy of two different treatments. Although more research is needed, the study’s results offer valuable insights for future clinical trials tackling this challenging disorder.

The challenges of cell therapy for cerebral palsy

Over the past two decades, cell therapy has emerged as a promising treatment for cerebral palsy. In particular, mononuclear cells from cord blood (UCB-MNCs) and mesenchymal stem cells from cord tissue (UCT-MSCs) have proven to be a safe and effective therapy. Many clinical trials have obtained results showing improvements in patients’ motor function through these cells’ anti-inflammatory, neuroprotective and regenerative properties.

However, efforts to pinpoint the best treatment method have been stymied by significant variations in trial parameters. Differences from study to study can include the type and severity of cerebral palsy, the age of the patients, the cell type, dose and delivery method, whether the study is open-label or blinded, and even the methods and time periods used to monitor improvement. Consequently, no two studies are alike, and results cannot be directly compared.[1][2]

Study methods and goal

The new study, conducted in Iran, is a pooled analysis of the results of two studies, one on UCB-MNTs and one on UCT-MSCs. Both studies were conducted in the same research centre; moreover, to aid in the comparison, the research methodology and other variables were kept the same as much as possible.[3][4][5]

The study patients were aged 4-14 and had spastic cerebral palsy with white matter lesions. After eligibility screening, 108 patients were randomly assigned to the two treatment arms or a control group. Treatment was done via intrathecal (into the spinal fluid) injection, with the control group receiving a sham procedure instead. Researchers then assessed patients’ motor function, quality of life, disability and spasticity after 1, 3, 6 and 12 months.

Both individual studies were double-blinded. Furthermore, all statistical analysis, both for individual studies and for the final pooled comparison, was performed by a blinded statistician.

The individual studies aimed to confirm that UCB-MNCs and UCT-MSCs are a safe and effective treatment for cerebral palsy. Following that, the pooled study analysis compared the effects of the UCB-MNC treatment to those of the UCT-MSC treatment across the study period.

Study results

Both the UCB-MNC treatment and the UCT-MSC treatment reported positive results over time when compared to the control group. Patients in both groups showed improvement in gross motor function and quality of life, as well as reduction in disability and spasticity.[4][5]

As the figure above shows, researchers found that the UCB-MNC treatment group showed stronger improvements in motor function early on. However, both the UCB-MNC and UCT-MSC groups achieved the same level of improvement at 6 months post treatment. At twelve months after treatment, there was some gradual deterioration of the improvements; however, researchers noted that UCT-MSCs did seem to result in more sustainable changes, with patients seeing less deterioration compared to the UCB-MNC group.[3]

Due to this deterioration, researchers posit that repeated doses at regular intervals may be the best route to continued improvement.[1] They also suggest that future trials should investigate treatments combining both UCB-MNCs and UCT-MSCs, as it may prove more effective than individual ones.[3]

The future of medicine

Researchers stress that this study is only a start, and further comparative trials and research are needed. Although both UCB-MNCs and UCT-MSCs offer positive results, there is still no certainty on which cell type and source will prove most effective treatment. This is true not only for cerebral palsy, but also for other illnesses and diseases for which an effective treatment is still being sought.

This uncertainty highlights the importance of comprehensive stem cell banking. By storing as many stem cell sources as possible, you could equip your baby and family with the broadest range of options for future regenerative therapies.

Scientists have shown that muscle patches grown from stem cells can be used to strengthen and help repair a failing heart. In a breakthrough clinical trial, ten patches containing 400 million cells were implanted on the heart of a 46-year-old woman who was suffering from heart failure. The results, along with results from earlier studies which tested the same procedure in monkeys, have been published in Nature. [1]

What is heart failure?

Heart failure is when the heart is too weak or stiff and, as a result, cannot pump blood around the body as well as it should. It can have a variety of causes, from heart disease and heart attacks to high blood pressure and inflammation.[2][3]

Heart failure is a long-term condition which gradually gets worse over time. Currently, it is considered an incurable condition; it can only be treated to keep the symptoms under control with medication and, sometimes, surgery. In severe cases of heart failure, a heart transplant may be necessary. However, there is a shortage of hearts for transplantation, so patients may have to wait several years before one becomes available.[4]

Development of the therapy

The team of researchers, led by Prof. Zimmermann from University Medical Center Göttingen, Germany, coaxed stem cells to grow into heart muscle and connective tissue cells. They then mixed these cells with collagen gel to create patches which could be applied to the outside surface of the heart using a minimally invasive surgery.

After initial studies in vitro and in small animal models of heart failure confirmed the treatment had potential, the patches were first tested in monkeys. The team implanted the patches into six rhesus macaques with heart failure. Three of the monkeys received two patches, while the other three received five. These monkeys were also all treated with immunosuppressive drugs. A second group of seven monkeys remained untreated as a control.

The implanted cells remained smaller than the monkeys’ own heart muscle cells. However, the patches led to an improvement in heart function compared to the control monkeys, thickening the heart’s muscle and increasing its pumping power.[5]

First in-human trial

The success of the trial in monkeys led to the approval of a first-in-human phase 1/2 trial, called BioVAT-HF, which began in 2021 and is currently ongoing.[6][7][8]

The trial has so far recruited 19 patients. The first of these, a 46-year-old woman, had severe heart failure and was waiting for a heart transplant.[1] The researcher team implanted the muscle patches on her heart; she also received immunosuppressive drugs of the same type normally used for transplants. Three months later, the patient was lucky enough to be the recipient of a successful heart transplant.

Upon analysis of her old heart, scientists found that the implanted patches had survived and had formed blood vessels. In other words, they had integrated with the heart without any side effects.

The therapy is still in the early stages of research, and Zimmermann is very clear that it is not yet a replacement for a heart transplant. Rather, it is a supportive treatment for patients in advanced stages of heart failure, who are waiting for a transplant and are under palliative care.

Still, these are incredibly exciting results, which could prove to be a game-changer for the treatment of heart failure. The research team is continuing the clinical trial. In addition, they are testing new patch designs in monkeys in hopes of minimising the need for immunosuppressive drugs.

Stem cells: the future of medicine

This study is one more example of how stem cells are shaping research through their applications in regenerative medicine.

The stem cells used in this particular clinical trial are allogeneic (donor) induced pluripotent stem cells (iPSCs). When receiving a donor transplant, there is always a risk of rejection, hence the need for immunosuppressive drugs.

Your baby’s umbilical cord is a rich source of stem cells, among the most naïve and potent your baby will ever have. They could be used for similar therapies in the future, should your baby need them. What’s more, they could be used without risk of rejection: they are your baby’s own cells, their own perfect genetic match.

You only get one opportunity to collect and store these cells: in the 15 minutes after your baby is born. To find out more about how you can preserve this precious resource, fill in the form below to request your free guide to cord blood banking.

A recent study, carried out both in vitro and in vivo on a mouse model, has found that extracellular vesicles derived from adipose (fat) and umbilical cord mesenchymal stem cells could have a regenerative effect on sun-damaged skin.[1]

Sun damage causes and consequences

Unprotected exposure to harmful ultraviolet (UV) rays from the sun damages the DNA in your skin, ageing it prematurely. This is called photoaging, or sun damage, and can take several forms:[2] [3] [4]

Wrinkles and skin thickening: UV rays break down collagen and elastin, proteins which give your skin its structure and elasticity. As a result, skin becomes thicker and wrinkled over time, beyond what would normally be caused by ageing.
Sun spots, redness or blotchiness: skin cells produce melanin as a reaction to UV rays, in an attempt to protect against further sun damage. This is the same process that gives you a tan. However, over time, the damaged skin becomes permanently, unevenly pigmented, causing darker patches often called sun spots. This can also take the form of broken blood vessels, causing permanent redness or blotchiness. This happens particularly in areas frequently exposed to the sun, such as the face and hands.
Skin cancer: too much UV exposure can cause skin cancer. In the UK, overexposure to UV radiation is the cause of 85% of cases of melanoma skin cancers.[5]

What are extracellular vesicles?

Extracellular vesicles are tiny particles which are generated from cells. They can carry important biomolecules, like fats and proteins, to other cells, working as a messenger of sorts.

Because the contents of extracellular vesicles can vary depending on the originating cells, scientists believe they could be of great importance in medicine. They could serve as a prognostic tool to predict the likely course of diseases, as well as help to cure them.[6]

In particular, extracellular vesicles derived from mesenchymal stem cells could inherit their regenerative properties, and have been a recent focus of research for their therapeutic potential.

What did the study find?

In the study, scientists from Peking Union Medical College, Beijing, China, aimed to investigate the effects of extracellular vesicles derived from adipose mesenchymal stem cells (AMSC-EVs) and umbilical cord mesenchymal stem cells (HUMSC-EVs) on photoaging.

In vitro, AMSC-EVs and HUMSC-EVs had positive effects on keratinocytes (cells which make up the outermost layer of the skin) and fibroblasts (cells which make up the connective tissue in the middle layer of the skin) that had been exposed to UV radiation. Treatment with EVs lowered inflammation and reduced the levels at which various biomarkers of senescence (ageing) were present in cells. Moreover, the treatment boosted cell proliferation and migration, properties which make skin cells better able to heal damage. Similar protective and regenerative effects were also observed using an in-vitro, full-thickness model of human skin.

These positive results prompted further analysis in vivo, using nude mice. The mice were randomly split into four groups, keeping one as the control. The other three groups were first exposed to high doses of UV radiation, then treated, respectively, with phosphate-buffered saline (PBS) as a placebo, with AMSC-EVs and with HUMSC-EVs.

All three groups exposed to UV initially developed deep, wide wrinkles. By the end of the observation period, however, the skin of mice treated with EV showed significantly fewer and thinner wrinkles. Skin analysis showed that EV treatment helped the skin recover water content, and reversed the epidermal thickening caused by UV radiation. The treatment also improved collagen and elastin levels and reduced inflammation. Additionally, there were fewer biomarkers of ageing in the skin cells of treated mice.

The benefits of stem cell banking

Both types of EVs studied proved effective in mitigating photoaging. However, the researchers noted that, in the mouse model, the effects of EVs derived from umbilical cord MSCs seemed better, from a therapeutic point of view, than those of EVs derived from fat tissue MSCs. The skin of the mice in the HUMSC-EV treatment group was noticeably less wrinkled. Additionally, the skin’s water content was much closer to that of the mice who had not been exposed to UV radiation at all, as was the epidermal thickness.

Furthermore, the process of collecting fat tissue for therapies is inherently invasive, but must be undergone if patients wish to use autologous (their own) stem cells as a therapeutic source. Conversely, the collection of stem cells from the umbilical cord is a painless, entirely non-invasive process; however, the cord must have been collected immediately after birth, and the cells and tissues cryogenically stored for future use. If this was not done, the only way to access therapies based on umbilical cord stem cells is the use of allogeneic (donor) cords – something which can encounter any number of issues, from lack of availability to incompatibility or rejection.

After two planned transplants from unrelated donors fell through at the very last minute, Australian three-year-old Tommy Bacon is now in remission from a rare, dangerous form of leukaemia following a transplant of the stem cells from his baby sister’s cord blood.[1]

Tommy’s story

Tommy fell ill not long after his parents discovered they were expecting a second child – a baby girl. When he first started showing signs of illness, his parents and their doctor were not immediately alarmed. They assumed it was just a case of the usual germs picked up at daycare, which he had recently begun attending.

After he developed tonsillitis during a family trip to the UK in May 2023, however, his parents took him to the hospital and insisted he should be admitted. Tests eventually revealed that he had leukaemia. More specifically, he had a form of the disease called juvenile myelomonocytic leukaemia (JMML). What’s worse, he had one of the most high-risk, aggressive variants.

JMML is incredibly rare, with only 1-2 children out of one million being diagnosed with it every year[2]. A stem cell transplant is the only curative treatment option. Without a transplant, however, a child with an aggressive variant of JMML could survive for less than a year.[3]

The search for a donor

Australia’s donor registry had no donor compatible with Tommy, so his parents started a donor drive. Eventually, an international donor was found. Unfortunately, however, the donor pulled out of the donation process a week before Tommy was due to start his pre-transplant chemotherapy.

By then, Tommy’s baby sister’s due date was fast approaching, and his parents booked a date for the induction. On the day they were going into hospital, a phone call came that a second donor had been found for Tommy. Still, they decided to have their baby girl’s cord blood collected and stored with an Australian cord blood bank, just in case – although they knew it wasn’t guaranteed that she would be a match for Tommy.

Not long after baby Aria’s birth, the second donor, too, pulled out. The family was heartbroken.

A search for a third donor got underway, but Tommy didn’t have long. Because of this, a decision was made to prepare Tommy’s dad as a half-matched (haploidentical) donor. Such a transplant would not have been ideal, since haploidentical transplant recipients are at higher risk of developing post-transplant complications[4]. Absent a perfect match, though, this was Tommy’s last hope.

Then, the cord blood bank called: they had tested Aria’s cord blood, and she was a perfect match for Tommy.

Within a few weeks, Tommy received his transplant. Four months later, he was in remission.

The importance of family cord blood banking

Tommy’s story highlights the importance of family stem cell banking. By choosing to bank your baby’s cord blood stem cells, they will always be ready and waiting should your baby, or another family member, need them.

Their cord blood stem cells are guaranteed to be their own perfect genetic match. There is also a 25% chance they will be a perfect match for a sibling, and a 50% chance of a partial match. Moreover, they are always a partial match for both parents. This is why it can be so important to bank cord blood for every baby in the family, rather than just one.

Stem cells are being heavily investigated in the field of regenerative medicine to treat a wide variety of illnesses and injuries that are currently considered incurable. There are over 7500 clinical trials currently investigating both autologous (a patient’s own stem cells) and allogeneic (donor stem cells) uses of stem cells, in the hopes of developing new therapies.

These therapies aim to take advantage of the regenerative qualities of stem cells to aid in healing injuries such as spinal cord damage, heart disease, brain injury, arthritis and type 1 diabetes.

By saving your baby’s cord blood stem cells, you can give your baby and family a better chance of accessing these therapies, should they need one in the future.

“I would strongly recommend that if you’re thinking about getting cord blood collected, do it!” says Tommy’s mum, Kylie. “If it can change a life in such a huge way, why would you not?”[5]

A 25-year-old woman from China is the first in the world to have been cured from type 1 diabetes, following an injection of islet cells derived from her own reprogrammed stem cells.

The study, published in the Cell journal, offers real hope to the millions of people worldwide suffering from this disease.

What is type 1 diabetes?

Type 1 diabetes is an autoimmune disease that causes the body’s own immune system to mistakenly attack and destroy insulin-producing cells in the pancreas.[1]

Insulin is a hormone which moves glucose (sugar) from the bloodstream into cells, where it is used for energy, and also helps store any extra glucose.[2]

Without insulin, glucose instead accumulates in the blood, causing a host of severe complications including vision loss, nerve damage, kidney failure, and non-healing ulcers that lead to lower limb amputations.[3]

This means people suffering from type 1 diabetes are dependent on external sources of insulin (through injections or a pump), and have to track and manage their blood sugar levels carefully.

How was the cure developed?

A team at Peking University, Beijing, China, extracted cells from three patients with type 1 diabetes and reverted them to a pluripotent state, from which they could be converted to different cell types in the body. These induced pluripotent stem cells (iPSC) were then used to generate clusters of islet cells, which would then be transplanted back into the patients.

Two and a half months later, the first patient to receive the transplant was producing enough insulin to no longer need external injections; she has remained insulin independent since, for more than a year.

Deng Hongkui, the lead scientist in the study, states the results for the other two patients in the study are also very positive. Those patients would have reached the one-year mark in November; it is hoped that when the results are published the trial could be expanded to more patients.[4]

Why is this trial important?

Islet cell transplantation can be an effective treatment for diabetes. In the past, this has relied on islet cells collected from organ donors, which are not sufficient to meet growing demand and require transplant recipients to use immune-suppressant medication to prevent transplant rejection.

A novel therapy developed by Vertex, currently undergoing clinical trials, aims to solve that issue by deriving islet cells from stem cells; however, this therapy also uses donated stem cells as a source, and thus requires the use of immune-suppressant medication.

It is hoped that the use of autologous (own) stem cells will remove the need for this medication. Since the patient studied was already on immune-suppressants due to a liver transplant, this is not a certainty; because type 1 diabetes is an autoimmune condition, there is still a risk that the immune system could attack the newly-transplanted islets regardless. However, Deng and his team aim to develop islet cells that can entirely evade the immune response.

The importance of banking stem cells

Although further study is required to evaluate the effectiveness of this therapy, breakthroughs like this highlight the potential of stem cells in the development of treatments for life-altering, chronic conditions such as type 1 diabetes.

By banking your baby’s cord stem cells, you can make sure they can be used for regenerative therapies like this, should your baby them in the future. To find out more about saving these powerful cells for your baby, download your free Welcome Pack by filling in the form below.

A new study on the effectiveness of treatment for spinal cord injuries indicates that a combination therapy, including epidural electrical stimulation (EES) as well as neural stem cells and umbilical cord stem cells, could offer better results than any one treatment on its own.

What is spinal cord injury?

Spinal cord injury is a debilitating, disabling neurological condition resulting from damage to the spinal cord, or to the nerves at the end of the spinal canal. This is most frequently caused by traumatic occurrences such as vehicle accidents, falls, sport injuries or violence, but may also be caused by tumours, infections or degenerative conditions.

Spinal cord injury causes partial or complete loss of sensation and function below the level of the injury, commonly resulting in paralysis (paraplegia or quadriplegia), loss of bladder and bowel control, and breathing issues.[1]

What therapies are currently available?

At present, there are no known therapies that would reverse the initial injury and return an injured spinal cord to full function.[2] Current treatments for spinal cord injury focus on limiting what is called the secondary injury cascade, ideally preventing further damage and thus further loss of feeling and motor function.[3] These methods include surgery, medication, physical therapy and rehabilitation, and assistive devices such as braces or wheelchairs.

What is epidural electrical stimulation for spinal cord injury?

In epidural electrical stimulation, an array of electrodes is implanted along the spinal cord through a surgical procedure called a laminectomy. The stimulation provided by the electrical pulses generated by these electrodes could help in the recovery of functionality following spinal cord injury, improving patients’ ability to walk and stand as well as aiding with bladder and bowel control.[3] [4]

How could stem cells help?

By leveraging the regenerative properties of stem cells, it is hoped that a stem cell treatment could repair and regenerate damaged spinal cord tissue.

This could mean protecting what neurons remain intact, repairing the protective myelin sheath on damaged ones, thus restoring their ability to conduct nerve signals, and replacing lost ones. Stem cells also have the ability to modulate the body’s immune response, and could reduce inflammation and mitigate the secondary damage that follows the initial injury.[5]

There are currently several clinical trials studying the application of stem cells for spinal cord injury. Although more research is needed, results so far are promising, including the high-profile case study of a man who has regained the ability to walk.[6]

What has the new study found?

Researchers at Xi’an Jiaotong University, China, set out to test the effectiveness of a therapy combining both epidural electrical stimulation and stem cell injections, using a mouse model of spinal cord injury.[7]

The study involved four different groups of mice: a group which was treated with EES alone, a group which was treated with a mix of mouse neural stem cells (NSCs) as well as human umbilical cord mesenchymal stem cells (hUCMSCs), a group which received both treatments and a control group in which the spinal cord injury was left untreated. The mice in all groups were monitored and assessed for a period of two months.

Following the injury, all mice had complete loss of function in their hind limbs; a week post-injury, mice in the treatment groups underwent their respective treatments. At the end of the monitoring period, mice in the control group were still unable to support themselves on their hind limbs. Conversely, some mice in the EES group were able to achieve paw standing; mice in the hUCMSC group also achieved this milestone, in a more frequent and sustained manner. Mice in the combined treatment group not only achieved paw standing, but also showed improved motor coordination. Swimming and gait analysis tests corroborated these findings, with the hUCMSC group doing better than the EES group, both doing better than the control and the combined treatment group doing best of all.

What’s next?

Both EES and stem cell transplants are currently the subject of clinical trials to test their effectiveness in the treatment of spinal cord injury. As the new study shows, it is entirely possible that the best treatment will be a combination of both, but more research is required on each individual treatment before the combination therapy can be tested in humans.

What is undeniable is that the number of studies and clinical trials examining the regenerative power of stem cells and their potential for treating currently incurable diseases and injuries continues to grow.

England flanker Tom Curry is undergoing stem cell therapy as a follow-up to last year’s career-saving surgery.[1]

Suffering from chronic hip pain and reduced range of motion, Curry was diagnosed with femoroacetabular impingement syndrome, where the ball of the hip joint is abnormally shaped, causing uneven wear and tear in the joint resulting in cartilage and bone damage.[2][3]

In Curry’s case, there was what was defined as an arthritic change within the hip[4] – labrum and cartilage tears, as well as abnormal bone growth. This was corrected in a six-hour surgery, which reshaped the ball of his hip and repaired the labrum and cartilage via a stem cell transplant.[2]

To fix the tears in Curry’s cartilage, leading hip surgeon Damian Griffin placed a synthetic cartilage graft in the joint and applied stem cells taken from Curry’s bone marrow to it to grow a new surface within the joint.[5] The procedure is performed arthroscopically (keyhole surgery), and it has a much shorter recovery time and carries less risk than surgeries involving metal implants, such as a hip resurfacing, where metal surfaces are used to cover the joint,[6] or a complete hip replacement.[7]

Now, Curry is undergoing another stem cell therapy in a bid to make it to the 2027 Rugby World Cup without needing more surgery.[1] There are fewer details available about this therapy, but it has been stated to be a stem cell injection in his hip to help bone growth.

How can stem cells help with injury recovery?

Stem cells possess remarkable regenerative potential, which therapies and procedures like those Curry is undergoing take advantage of. The cells that make up bone and cartilage typically derive from mesenchymal stem cells (MSCs), which, in addition to their ability to turn into a variety of specialised cell types, also have anti-inflammatory properties. This makes them ideal to help repair damaged tissue, particularly cartilage, which has very limited regenerative capacity of its own.

Curry is far from the only elite athlete to turn to stem cells to get back to form. Footballer Cristiano Ronaldo used stem cell therapies to successfully address knee problems[8], while tennis great Rafael Nadal treated both chronic knee issues and a long-standing back complaint[8][9]. Boxing legend Mike Tyson also had stem cell therapy.[8]

Today marks World Cord Blood Day—a day dedicated to highlighting the medical breakthrough that began 36 years ago, in 1988, with a single transplant. That cord blood transplant opened the door to a new era in medicine. Since then, stem cells from cord blood have transformed countless lives, offering hope to those battling over 80 serious diseases including leukaemia, sickle cell anaemia, lymphoma, and more.

Once dismissed as medical waste, cord blood’s potential to heal is becoming more and more recognised, with over 60,000 transplants since 1988. Today, stem cells are the key players in regenerative medicine, studied in thousands of labs and clinical trials around the world. Scientists are exploring their potential to treat conditions as varied as bone fractures, spinal cord injuries, arthritis, and even Crohn’s disease.

Yet, despite this remarkable potential, too often cord blood is still discarded after birth, lost forever. This is why World Cord Blood Day was created: to shine a light on the therapeutic power of cord blood and to encourage more families to preserve this incredible resource for the future.

As research has continued though, it is no longer just cord blood that holds such promise, but also the cord tissue and placental stem cells which hold immense potential in regenerative medicine.

Cord blood news

A lot has happened in the cord blood field since last year. Here are some news you may want to catch up on if you’ve missed them…

Researchers in China found that umbilical cord stem cells could aid in healing intestinal ulcers caused by Crohn’s disease.
A study found that umbilical cord stem cell therapy could improve ovarian function, a potentially important step towards overcoming the ‘biological clock’ of waning fertility.
A five-year-old boy with a rare genetic disorder received a life-changing transplant of cord blood stem cells that had been stored by the NHS for 15 years.
A clinical trial investigating the use of umbilical cord stem cells to treat chronic heart failure is underway.
Umbilical cord stem cells are being researched as a treatment for acute liver failure.
A new therapy could improve treatment outcomes for patients with Krabbe disease following a stem cell transplant.
A recent report by the Parents’ Guide to Cord Blood Foundation highlighted continued interest in treatments based on umbilical cord stem cells in the medical research field.
Haplo cord blood transplants, combining stem cells from a cord blood unit and a bone marrow donor, improve survival rates post-transplant and reduce the risk of graft-versus-host disease.
Umbilical cord exosomes could be used in developing life-changing therapies for a variety of conditions.

How can I bank my baby’s cord blood?

If you want to save this precious resource rather than having it thrown away, both public and private banking are available options.

Public banking means the cord blood stem cells are stored in a cord bank that makes them accessible to anyone who might need them. The NHS public cord bank accepts donations if you are giving birth at one of three hospitals; the Anthony Nolan charity public cord bank accepts donations from a further five hospitals.

Alternatively, you can choose to bank your baby’s cord blood privately, storing the stem cells solely for your family’s own use. They will be ready and waiting should your baby ever need them for treatment, and could be useful for family members, too – there is a 25% chance they would be an exact match for a sibling, or 75% chance of a partial match. They are also a guaranteed partial match for parents.

Everything about our services has been tailored to provide the maximum potential benefit to parents who store their baby’s stem cells with us, such as our advanced processing technology that retains up to three times more stem cells than industry-standard processing methods, meaning full compatibility with delayed and optimal cord clamping. We are also the only UK cord blood bank to offer placenta and amnion storage.

The results reported from Phase II of the first FDA-approved trial for the treatment of multiple sclerosis (MS) using stem cells are highly promising, suggesting that stem cells could be a viable treatment option to help improve the lives of those with the condition. [1]

What is the MS trial?

The Phase II trial, which was carried out by The Tisch MS Research Center of New York, constitutes the next stage in the development of the groundbreaking research signalled by the results from Phase I, the first FDA-approved trial to explore the injection of stem cells for MS.

The Phase II trial involved 54 patients split between a test group and a control group in a randomised, double-blind, placebo-controlled study.

Members of each group received 6 injections of either autologous (meaning their own) mesenchymal stem cell-derived neural progenitors (MSC-NPs) or saline placebo every two months.

These injections were administered into the cerebrospinal fluid of multiple sclerosis patients.

The study utilised a cross-over model by which patients who received the stem cell injections in year 1 were then given the saline placebo in year 2 and vice versa.

How does the stem cell treatment work?

Building on their findings from Phase I, researchers identified MSC-NPs for the treatment having ascertained that they promote tissue regeneration and immunomodulatory effects, in addition to being safe and well tolerated. [2]

MSC-NPs are a subpopulation of mesenchymal stem cells that can upregulate growth factors like hepatocyte growth factor (HGF), and minimise ectopic differentiation – essentially, the abnormal differentiation of cells.

By injecting them into the cerebrospinal fluid – a process called intrathecal (IE) injection – researchers found in an experimental autoimmune encephalomyelitis (EAE – an accepted way of modelling the effects of MS) mouse model that MSC-NPs were associated with increased spinal cord myelination, neurological recovery and reduced immune infiltration into the central nervous system. [3]

What were the results?

The results of the Phase II trial demonstrated huge promise for the use of stem cells in treating MS.

Patients requiring walking assistance saw significant improvements in both a timed 25-foot walk test and a 6 minute walking test than those in the control group.

Additionally, treatment recipients demonstrated improved bladder function, with 69% showing improvements in post-void residual volume.

Amongst the other findings were indicators that these stem cells could be helping to restore neuronal cells and reverse cognitive decline in patients with less advanced disease progression.

Furthermore, the stem cell treatment occasioned notable biomarker changes in cerebro-spinal fluid, especially with regards to the decreased levels of CCL2, a protein associated with inflammation, and the increased levels of MMP9, an indicator of the increased presence of reparative cells. [4]

Overall these findings are extremely promising, indicating that stem cells could be used in future treatments that may help to reverse many of the most debilitating aspects of multiple sclerosis, like disability.

The next stage in the study will be for researchers to investigate the effects of increasing the stem cell dosage.

What does this mean for cord blood banking?

This trial is just the latest example of the regenerative potential stem cells have to help treat life-changing conditions like MS.

As exemplified by this study, mesenchymal stem cells in particular, with their immunomodulatory and tissue repair properties, are especially promising.

Incredibly, the umbilical cord and placenta are one of the richest sources of these stem cells, but are routinely thrown away after birth.

By saving these for your baby, you could be giving them the key to future therapies for everything from cancer and stroke to diabetes and heart disease.

The potential offered by stem cells is vast, but you only get one chance to save baby’s stem cells, and that’s the day they’re born.

New research has demonstrated the significant role stem cells play in skin and hair development, which could lead to revolutionary new anti-ageing treatments. [1]

By identifying the ways in which the body grows skin, researchers believe that their findings could lead to the use of artificial skin in treatments for burns, wounds, and age-related degeneration.

The research was conducted as part of The Human Cell Atlas project, which aims to map the genetic instructions contained in every cell in the human body to discover how they work.

New discoveries about skin formation

The study looked at the role immune cells, specifically macrophages, play in the development of skin during pregnancy.

While macrophages – which are a type of white blood cell responsible for killing pathogens – are primarily known for their importance as part of the immune system, researchers sought to identify how they contribute to skin formation in a process known as morphogenesis.

In order to do this, a so called ‘reference atlas’ of prenatal skin (that is, skin that forms between 7-17 weeks after conception) was made using advanced techniques including single cell and spatial transcriptomics – a study of RNA molecules within both one and a population of cells – to detail how elements both within and between skin cells interact.

Their findings showed that interactions between immune cells like macrophages and non-immune cells were crucial for key processes in morphogenesis, including hair follicle development, scarless wound healing, and the formation of blood vessels in the skin. [2]

The important role of stem cells in determining skin formation

Researchers were able to verify their findings about the significant role played by immune cells in skin morphogenesis by comparing pre-natal and adult skin with a lab-grown skin model derived from stem cells.

The model, known as an organoid, successfully mimicked many aspects of skin and hair follicle development found in prenatal and adult skin.

However, it was only when researchers added macrophages that they found the model created blood vessel networks, confirming that immune cells play a more significant role in the development of skin than previously thought.

This stem-cell derived model of human skin is thought to have a vast array of possible therapeutic applications extending from use in identifying the development of conditions affecting skin and hair to providing a more accurate test material for future skin and hair treatments. [3]

Mesenchymal stem cells – key players in hair and skin formation

Another area researchers looked at during the study was the formation of hair follicles during prenatal development.

In earlier studies with mice, researchers identified special cells called pre-Dc cells that eventually become part of the hair follicle structure (called the dermal condensate, or Dc). [4]

Researchers identified similar cells in human prenatal skin and tracked how they developed into the Dc and another structure called the dermal papilla (Dp), which is important for hair growth.

Using various advanced methods, researchers were able to map out the development of these cells over time and predict their paths.

They found that certain early skin cells (fibroblasts) go down one of two routes: some become specialised for hair follicle formation, while others develop into more general skin cells.

As the hair-specific cells move toward the outer layer of the skin, they turn on genes that help them stick together and form the structures needed for hair growth.

The study also looked at how mesenchymal cells interact with skin’s outer (epithelial) cells during hair follicle formation.

They identified important signalling molecules, such as CXCL12, that help guide cell migration and organisation. Interestingly, immune cells were also predicted to assist with these processes. [5]

Discovering the genetic origins of skin and hair conditions

Having mapped how skin and hair developed in pre-natal skin, researchers turned to investigating the origins of certain skin and hair conditions.

They found that reduced hair growth (hypotrichosis) and abnormal hair shapes (like pili torti) are caused by specific genes that are active during early hair follicle development.

Similarly, they were able to identify that epidermolysis bullosa (EB) – a disorder that makes the skin fragile and prone to blistering – had its roots in the expression of the gene COL7A1 in several types of prenatal skin cells.

Researchers were again able to compare gene expression in prenatal skin with their stem cell-derived lab-grown skin models and found strong similarities, noting that while these diseases often stem from defects in skin structure, they are frequently worsened by immune system involvement. [6]

The importance of stem cells and cord blood banking

As this new research demonstrates, stem cells play a pivotal role in not only helping researchers to better understand the formation of vital organs, like skin, but also in helping to facilitate potential future therapies.

By being able to compare cells from both prenatal and adult skin with artificial lab-grown skin using stem cells, researchers were able to identify the hitherto unknown significance of immune cells in skin formation and accurately map the genetic instructions involved in growing skin.

In their paper published in Nature, The Human Cell Atlas team have achieved something remarkable: essentially providing a set of instructions for creating human skin.

Their research is being heralded as groundbreaking and for good reason. Their findings will help to contribute to the development of a range of therapies for genetic skin conditions, treatments for wounds and burns, and remedies that could help to rejuvenate skin.

While the stem cells utilised in this trial were from embryonic stem cells and induced pluripotent stem cells, the stem cells found in umbilical cord tissue have similarly huge potential in regenerative medicine.

In fact, and as we’ve shown previously, trials utilising mesenchymal stem cells – the same type as found in umbilical cord tissue – are already underway that could aid in the treatment of both hair loss and skin conditions like atopic dermatitis. [7] [8]

What’s clear is that stem cells are pivotal in both cutting edge research and the development of future regenerative therapies.

Unfortunately, the umbilical cord and placenta – both rich sources of stem cells – are routinely thrown away after birth. By saving these powerful stem cells for your baby, you could give them access to future therapies that are currently being developed using stem cell-based research as in this study.

A new study on cell therapy for cerebral palsy has, for the first time, directly compared the efficacy of two different treatments. Although more research is needed, the study’s results offer valuable insights for future clinical trials tackling this challenging disorder.

The challenges of cell therapy for cerebral palsy

Study methods and goal

Both individual studies were double-blinded. Furthermore, all statistical analysis, both for individual studies and for the final pooled comparison, was performed by a blinded statistician.

The individual studies aimed to confirm that UCB-MNCs and UCT-MSCs are a safe and effective treatment for cerebral palsy. Following that, the pooled study analysis compared the effects of the UCB-MNC treatment to those of the UCT-MSC treatment across the study period.

Study results

Both the UCB-MNC treatment and the UCT-MSC treatment reported positive results over time when compared to the control group. Patients in both groups showed improvement in gross motor function and quality of life, as well as reduction in disability and spasticity.[4][5]

Due to this deterioration, researchers posit that repeated doses at regular intervals may be the best route to continued improvement.[1] They also suggest that future trials should investigate treatments combining both UCB-MNCs and UCT-MSCs, as it may prove more effective than individual ones.[3]

The future of medicine

This uncertainty highlights the importance of comprehensive stem cell banking. By storing as many stem cell sources as possible, you could equip your baby and family with the broadest range of options for future regenerative therapies.

What is heart failure?

Heart failure is when the heart is too weak or stiff and, as a result, cannot pump blood around the body as well as it should. It can have a variety of causes, from heart disease and heart attacks to high blood pressure and inflammation.[2][3]

Development of the therapy

The implanted cells remained smaller than the monkeys’ own heart muscle cells. However, the patches led to an improvement in heart function compared to the control monkeys, thickening the heart’s muscle and increasing its pumping power.[5]

First in-human trial

The success of the trial in monkeys led to the approval of a first-in-human phase 1/2 trial, called BioVAT-HF, which began in 2021 and is currently ongoing.[6][7][8]

Upon analysis of her old heart, scientists found that the implanted patches had survived and had formed blood vessels. In other words, they had integrated with the heart without any side effects.

The therapy is still in the early stages of research, and Zimmermann is very clear that it is not yet a replacement for a heart transplant. Rather, it is a supportive treatment for patients in advanced stages of heart failure, who are waiting for a transplant and are under palliative care.

Still, these are incredibly exciting results, which could prove to be a game-changer for the treatment of heart failure. The research team is continuing the clinical trial. In addition, they are testing new patch designs in monkeys in hopes of minimising the need for immunosuppressive drugs.

Stem cells: the future of medicine

This study is one more example of how stem cells are shaping research through their applications in regenerative medicine.

The stem cells used in this particular clinical trial are allogeneic (donor) induced pluripotent stem cells (iPSCs). When receiving a donor transplant, there is always a risk of rejection, hence the need for immunosuppressive drugs.

You only get one opportunity to collect and store these cells: in the 15 minutes after your baby is born. To find out more about how you can preserve this precious resource, fill in the form below to request your free guide to cord blood banking.

A recent study, carried out both in vitro and in vivo on a mouse model, has found that extracellular vesicles derived from adipose (fat) and umbilical cord mesenchymal stem cells could have a regenerative effect on sun-damaged skin.[1]

Sun damage causes and consequences

Unprotected exposure to harmful ultraviolet (UV) rays from the sun damages the DNA in your skin, ageing it prematurely. This is called photoaging, or sun damage, and can take several forms:[2] [3] [4]

Wrinkles and skin thickening: UV rays break down collagen and elastin, proteins which give your skin its structure and elasticity. As a result, skin becomes thicker and wrinkled over time, beyond what would normally be caused by ageing.

Skin cancer: too much UV exposure can cause skin cancer. In the UK, overexposure to UV radiation is the cause of 85% of cases of melanoma skin cancers.[5]

What are extracellular vesicles?

Extracellular vesicles are tiny particles which are generated from cells. They can carry important biomolecules, like fats and proteins, to other cells, working as a messenger of sorts.

Because the contents of extracellular vesicles can vary depending on the originating cells, scientists believe they could be of great importance in medicine. They could serve as a prognostic tool to predict the likely course of diseases, as well as help to cure them.[6]

In particular, extracellular vesicles derived from mesenchymal stem cells could inherit their regenerative properties, and have been a recent focus of research for their therapeutic potential.

What did the study find?

In the study, scientists from Peking Union Medical College, Beijing, China, aimed to investigate the effects of extracellular vesicles derived from adipose mesenchymal stem cells (AMSC-EVs) and umbilical cord mesenchymal stem cells (HUMSC-EVs) on photoaging.

After two planned transplants from unrelated donors fell through at the very last minute, Australian three-year-old Tommy Bacon is now in remission from a rare, dangerous form of leukaemia following a transplant of the stem cells from his baby sister’s cord blood.[1]

Tommy’s story

JMML is incredibly rare, with only 1-2 children out of one million being diagnosed with it every year[2]. A stem cell transplant is the only curative treatment option. Without a transplant, however, a child with an aggressive variant of JMML could survive for less than a year.[3]

The search for a donor

Australia’s donor registry had no donor compatible with Tommy, so his parents started a donor drive. Eventually, an international donor was found. Unfortunately, however, the donor pulled out of the donation process a week before Tommy was due to start his pre-transplant chemotherapy.

Not long after baby Aria’s birth, the second donor, too, pulled out. The family was heartbroken.

Then, the cord blood bank called: they had tested Aria’s cord blood, and she was a perfect match for Tommy.

Within a few weeks, Tommy received his transplant. Four months later, he was in remission.

The importance of family cord blood banking

Tommy’s story highlights the importance of family stem cell banking. By choosing to bank your baby’s cord blood stem cells, they will always be ready and waiting should your baby, or another family member, need them.

These therapies aim to take advantage of the regenerative qualities of stem cells to aid in healing injuries such as spinal cord damage, heart disease, brain injury, arthritis and type 1 diabetes.

By saving your baby’s cord blood stem cells, you can give your baby and family a better chance of accessing these therapies, should they need one in the future.

“I would strongly recommend that if you’re thinking about getting cord blood collected, do it!” says Tommy’s mum, Kylie. “If it can change a life in such a huge way, why would you not?”[5]

A 25-year-old woman from China is the first in the world to have been cured from type 1 diabetes, following an injection of islet cells derived from her own reprogrammed stem cells.

The study, published in the Cell journal, offers real hope to the millions of people worldwide suffering from this disease.

What is type 1 diabetes?

Type 1 diabetes is an autoimmune disease that causes the body’s own immune system to mistakenly attack and destroy insulin-producing cells in the pancreas.[1]

Insulin is a hormone which moves glucose (sugar) from the bloodstream into cells, where it is used for energy, and also helps store any extra glucose.[2]

Without insulin, glucose instead accumulates in the blood, causing a host of severe complications including vision loss, nerve damage, kidney failure, and non-healing ulcers that lead to lower limb amputations.[3]

This means people suffering from type 1 diabetes are dependent on external sources of insulin (through injections or a pump), and have to track and manage their blood sugar levels carefully.

How was the cure developed?

Two and a half months later, the first patient to receive the transplant was producing enough insulin to no longer need external injections; she has remained insulin independent since, for more than a year.

Deng Hongkui, the lead scientist in the study, states the results for the other two patients in the study are also very positive. Those patients would have reached the one-year mark in November; it is hoped that when the results are published the trial could be expanded to more patients.[4]

Why is this trial important?

Islet cell transplantation can be an effective treatment for diabetes. In the past, this has relied on islet cells collected from organ donors, which are not sufficient to meet growing demand and require transplant recipients to use immune-suppressant medication to prevent transplant rejection.

A novel therapy developed by Vertex, currently undergoing clinical trials, aims to solve that issue by deriving islet cells from stem cells; however, this therapy also uses donated stem cells as a source, and thus requires the use of immune-suppressant medication.

The importance of banking stem cells

Although further study is required to evaluate the effectiveness of this therapy, breakthroughs like this highlight the potential of stem cells in the development of treatments for life-altering, chronic conditions such as type 1 diabetes.

By banking your baby’s cord stem cells, you can make sure they can be used for regenerative therapies like this, should your baby them in the future. To find out more about saving these powerful cells for your baby, download your free Welcome Pack by filling in the form below.
