Retinitis Pigmentosa Treatment Stem Cell
Different types of stem cells have been isolated from a range of tissues including preimplantation embryos, birth-associated tissues, fetuses, and adult organs. Based on the source, these cells can be generally classified into adult tissue-derived stem cells and embryo-derived stem cells. And based on biochemical and genomic markers, these stem cells can be mostly classified into mesenchymal stem cells, embryonic stem cells, hematopoietic stem cells, and stimulate pluripotent stem cells. Stem cell therapy is a new way for vision restitution in retinitis pigmentosa. Transplantation of stem cells that can be stimulated to turn into replacement photoreceptors and be helpful of outer retina cells can theoretically lead to treatments that restore visual function.
Despite the recent progress made by stem cell transplantation therapy as a New Treatment for Retinitis Pigmentosa, many challenges continue. Initially, the problem of low rate of stem cell endurance and migration requests to be resolved. Secondly, although the retina is being physically isolated from the immune system, the immune response that is triggered when stem cells are transplanted into the subretinal space for the period of therapy and hampers their endurance cannot be ignored.
