Stem Cells Restore Sight in Mouse Model of Retinitis Pigmentosa

An international research team led by Columbia successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa. This strategy could potentially become a new treatment for retinitis pigmentosa, a leading cause of blindness that affects approximately one in 3,000 to 4,000 people, or 1.5 million people worldwide. The study appeared in the journal Transplantation (March 27, 2010, print issue).
