Study Shows Stem Cells Can Preserve Vision

From sciencedaily:

"For the first time researchers have shown that transplanted stem cells can preserve and improve vision in eyes damaged by retinal disease. In the cover article in the November 2004 Investigative Ophthalmology and Visual Science, scientists from Harvard's Schepens Eye Research Institute describe results of a mouse study in which transplanted stem cells develop into retinal cells, prevent the death of 'at risk' retina cells in the recipient mice and improve the vision of treated mice."
