The Science Bit. Let’s Expand this Point
As we mentioned, people with Parkinson’s disease don’t have enough dopamine – the chemical that enables message to be sent to parts of the brain controlling movement and some forms of thinking.
So, we need dopamine-producing neurons.
Neurons transplanted into a patient can survive and work well, repairing and replacing damaged tissue. Thus, stem cells literally become dopamine-producing nerve cells, and the patient can regain much of their former movement and cognitive function.
It really is like giving someone their life back.
Currently, researchers can get stem cells from several sources, including embryos, blood cells taken from the umbilical cord at birth, and bone marrow. The elephant in the room should be addressed, of course: currently, rigorous ethical and regulatory frameworks surround all the work being done around this important study.
Strict legal guidelines govern every aspect. In fact, the Human Fertilisation and Embryology Act 1990 states that only early-stage embryos can be used in research – no more than 14 days old.
Trials are ongoing, and of course we’ll report any developments when we know more. We’re pleased to report, however, that Parkinson’s UK fully supports ongoing research (1).
