However, organ transplantation is lagging in the absence of adequate organ donations. Shortage of organs for transplantation is a challenge to developing countries like Nepal and developed countries like the USA and UK. Despite various efforts to increase the rate of organ donation, the problem persists. The primary reason for the failure to accomplish adequacy in organ do-nation is the immediate dependency on an available donor. On top of that, reluctance to decide on organ donation after death, regarded as an onerous moment, at least by the general public, has another impact on the subject.

Regenerative medicines look for novel therapies for severe injuries or chronic diseases, e.g., retina degeneration. Müller glia is the only retinal glia type with a common embryonic origin, with retinal neurons derived from the neural crest. Also, the lack of neurons in the retina does not automatically regenerate. Therefore, Müller glial cells, which make up about 5% of retinal cells, are a potent source for retinal regeneration. Following the retinal damage, Müller glial cells dedifferentiate and re-enter the cell cycle, producing multipotent progenitor cells. This feature leads to applying Müller glial cells in the regeneration of the retina.
