Stem cell therapy shows visionary promise

Madison, Wis. - For the millions of Americans whose vision is slowly ebbing due to degenerative diseases of the eye, the lowly neural progenitor cell may be riding to the rescue.

In a study in rats, neural progenitor cells derived from human fetal stem cells have been shown to protect the vision of animals with degenerative eye disease similar to the kinds of diseases that afflict ......

What was surprising, say Gamm and Lund, was that the cells alone demonstrated a remarkable ability to rescue vision.

"On their own, they were able to support retinal cells and keep them alive," says Lund, who has conducted pioneering studies of cell therapy for eye disease. "We didn't expect that at all. We've used a number of different cell types from different......

Gamm and Lund emphasize that the new work is preliminary, and that much remains to be done before the cells can ......
