“Not only did the new cells survive, and were found in later dissections, but they also integrated with the existing neuronal network – functioning like normal dopamine-producing brain cells and allowing gradually improved movement over a 12-month period.
“Although this is promising quality research, and the conclusions are backed up by solid data that comes from a variety of sources, including behavioural, brain scan and histological analysis, there are still major challenges ahead. We need to understand if these new transplanted cells would succumb to the same fate as the original cells that had previously died.
“There are also other types of brain cells that are affected by Parkinson’s, and additional work must be done to tackle those symptoms of the condition that are not caused by a lack of dopamine.”
