The preliminary findings, published online Jan. 23 in the journal The Lancet, represent a milestone in the therapeutic use of stem cells and may pave the way for a new therapy to treat eye diseases, the researchers said. Because this is the first time physicians have applied the power of regenerative medicine to eye disease, the clinical trials are being watched closely by scientists, stem-cell therapy advocates and the public.
