(July 30, 2014) — University of Kentucky biologist Ann Morris is studying retinal regeneration in zebrafish to find ways to combat human eye diseases.
The small, minnow-like fish have eyes that develop in a way very similar to humans. Unlike humans, however, zebrafish have the ability to regenerate retinal cells following an injury. Diseases of the retina are a leading cause of blindness in older adults.
“With zebrafish the embryos develop outside the mother, and they are completely transparent. And development occurs very rapidly," Morris said. "So we can study the process of the development of eye under the light microscope in a dish, and it only takes a couple days to happen."
