Role identified for key protein in regeneration of damaged newt retinas

(University of Tsukuba) University of Tsukuba-led researchers have identified a role for the Pax6 protein in deciding the fate of newt retinal cells. Normal newt retinal pigment epithelium cells enable retinal regeneration following injury, but those lacking Pax6 were unable to do so. Instead, they behaved like cells in human retinas by transforming to heal the wound but failing to renew the retina.
