This gives hope for a possible treatment for retinal degenerative and blinding diseases, all of which are currently incurable.
U.S. Researchers have restored vision in mice by activating stem cells in the retina to regrow damaged cells.
Zebrafish have the ability to restore their own vision using certain cells replace damaged retinal nerve cells. But retinas of mammals cannot fix their own damage.
In this study, researchers were able to activate new light receptors that integrated themselves into the retina and could sense light.
That allowed the brains of the mice to receive visual information and actually restored vision after four-to-six weeks.
You can read about the research in the journal, Nature.
