Skin cells from a donor were reprogrammed to become stem cells and then turned into a certain type of retinal cell that was transplanted onto the retina of the patient who has age-related macular degeneration. So far the man’s vision has not declined which means it might be working.

The use of donors to make reprogrammed stem cells is new but the idea is to create a stem cell bank where people that have the same antigen type can be recipients of the stem cell therapy. Very exciting times ahead!
