Stem cells to aid the blind NOV 24 2010
Clinical trials are about to begin where embryonic stem cells will be injected into the eyes of people with Stargardt's macular degeneration.
Robert Lanza, the company's chief scientific officer, said that the first patient could receive the stem cell transplants early in the new year and although the trial is designed primarily to assess safety, the first signs of visual improvement may be apparent within weeks. "Talking to the clinicians, we could see something in six weeks, that's when we think we may see some improvements. It really depends on individual patients but that's a reasonable time frame when something may start to happen," Dr Lanza said.
