“You can blind or seriously damage a zebrafish, and they will regrow their eye in a matter of weeks,” says James Patton, a biologist at Vanderbilt University The fish can do this because of those Müller glia cells in the retina Behaving like stem cells, they can regrow the retina and replace all the damaged neurons
