Muller glia
Müller glia, or Müller cells, are glia found in the vertebrate retina, which normally serve the functions of any normal glial cells. However, following injury to the retina, it has been seen that Müller glia undergo dedifferentiation into multipotent progenitor cells. At this point, the progenitor cell can divide and differentiate into a number of retinal cell types, including photoreceptors, that may have been damaged during injury.[citation needed] Additionally, recently published research has shown that Müller cells act as a light collector in the mammalian eye, analogous to a fiber optic plate, which funnels light to the rods and cone cells.
Research Potential
Müller glia are currently being studied in labs all over the United States as they are involved in neural regeneration, a phenomenon that does not occur in humans[dubious ]. Published papers have studied Müller glia in both zebrafish[1] and chicken[2] retina, and further research could help towards solutions for the blind or visually impaired.
