flag A University of Michigan trial using stem cells improved vision in advanced dry AMD patients with no serious side effects.

flag A clinical trial at the University of Michigan using adult stem cell transplants to treat advanced dry age-related macular degeneration (AMD) has shown early success, with six patients experiencing improved vision and no serious side effects. flag The treatment, involving retinal pigment epithelial cells from donor eye tissue, led to an average gain of 21 letters on an eye chart one year later, with no improvement in untreated eyes. flag The NIH-funded study, published in Cell Stem Cell, is expanding to include 12 more participants receiving higher cell doses. flag Researchers call the results promising and unprecedented for advanced AMD, a condition affecting about 20 million Americans that currently has no vision-restoring treatment.
