Researchers discover stem cells in the optic nerve that enable preservation of vision
Researchers at the University of Maryland School of Medicine (UMSOM) have for the first time identified stem cells in the region of the optic nerve, which transmits signals from the eye to the brain. The finding, published this week in the journal Proceedings of the National Academy of Sciences (PNAS), presents a new theory on why the most common form of glaucoma may develop and provides potential new ways to treat a leading cause of blindness in American adults.
