Revolutionary Stem Cell Therapy Restores Vision in Blinding Eye Diseases.

A preclinical study using stem cells to produce photoreceptor progenitor cells and transplanting them into experimental models of damaged retinas has resulted in significant vision recovery. This finding marks a first step toward potentially restoring vision in eye diseases characterized by photoreceptor loss, including age-related macular degeneration and retinitis pigmentosa. The next challenge for the researchers is to explore the efficacy of their method in models of photoreceptor degeneration that more closely match the human condition.
