Müller cells; Muller glia

Müller glia, or Müller cells, are glial cells found in the retina, which serve as support cells for the neurons of the retina as all glial cells do.

However, following injury to the retina, it has been shown in zebrafish that Müller glia undergo dedifferentiation into multipotent progenitor cells. The progenitor cell can then divide and differentiate into a number of retinal cell types, including photoreceptor cells, that may have been damaged during injury.

Additionally, further research has shown that Müller glia act as light collectors in the mammalian eye, analogous to the fiber optic plate, funneling light to the rod and cone photoreceptors.
