Parkinson's disease stem cell therapy starts clinical trials.

According to the US Daily Science website, three institutions, including the Keck School of Medicine at the University of Southern California, are jointly launching a cutting-edge clinical trial. They will test a new type of stem cell therapy on 12 patients with moderate to severe Parkinson's disease by implanting laboratory-cultured dopamine-producing cells into the brain to restore the brain's ability to produce dopamine naturally, in hopes of slowing the progression of Parkinson's disease and improving patients' motor function.
