Summary:
Researchers report that cells created from human embryonic stem cells slowed vision loss when injected into the eyes of rats with a disease similar to macular degeneration, the leading cause of blindness in people older than 55. The experiments do not prove that the cells, obtained through the destruction of human embryos, will work in people. But by showing that the cells have the potential to fill in for failing cells in the retina, experts said, the work may help justify trying the technique in humans.
