Scientists used human stem cells to restore a monkey’s vision

A group of scientists restored vision in a monkey by using human stem cells to fix a hole in its retina. The research could open new doors for vision treatment in humans and other animals, too.

A new study published this month in Stem Cell Reports more thoroughly describes this amazing feat and shows a massive leap forward in the progress toward retinal transplantation. The researchers describe how they used human stem cells to create a patch, which they then used to fix the macular hole in the monkey’s eye.
