Biotech company says it's implanted dopamine-making cells in patients brains.
A California-based biotech company says it's successfully implanted lab-made neurons in Parkinson's patients' brains to stimulate a dopamine response — and if it works as intended, it could be a substantial advance in fighting the disease. As MIT Technology Review reports , the early stem cell experiment, which was meant to test whether the procedure is safe, appears to have succeeded at that goal. The trial included 12 people with Parkinson's, a debilitating progressive disease characterized by a shortage of dopamine, and was run by BlueRock Therapeutics, a subsidiary of the pharmaceutical giant Bayer. The lab-made neurons were implanted for a year before results were taken, and as researchers told attendees of the International Congress for Parkinson’s Disease and Movement Disorder in Copenhagen at the end of August, the implanted cells seem to have survived — and, in a particularly exciting twist, there are indications that they may be reducing the patients' sy...
