For the first time, stem cells have been injected into the brain of an elderly stroke victim to see how safe the procedure is. The trial is taking place in Glasgow and researchers say up to 12 more patients will be given progressivly higher doses. Professor Keith Muir, a neuroscientist at Glasgow University and a consultant neurologist at Southern General Hospital, where the trials are taking place, said that if the trials go well, it would lead to more-detailed research, according to a report in the BBC. "We hope that in the future it will lead to larger studies to determine the effectiveness of stem cells on the disabilities that result from strokes," he says. Report
