Embryonic stem cells restore some vision to blind patient

For the first time, an experimental treatment made from human embryonic stem cells has shown evidence of helping someone, partially restoring sight to two people suffering from slowly progressing forms of blindness. Although the purpose of the experiment was to test the safety of stem cells injected into the eye, both patients “had measurable improvement in their vision that persisted through the duration of the study,” said Robert Lanza, chief scientific officer at Advanced Cell Technology, the Massachusetts biotech company that sponsored the closely watched experiment.  Source: Washington Post 23/1/2012
