Scientists have made huge advances by using stem cell therapy to cure diseases in animal models. Testing these experimental cell therapy for blind humans poses some unique challenges. This is something that the scientists wish to try out soon and effectively. There are several challenges which lay in front of scientists when considering stem cell therapy in humans.

One is proving that the use of Stem Cell For Blinds is safe to use . Another challenge that the body faces is the issue of immune rejection of the transplanted cells. In such cases care is required. When introducing foreign cells in the body it requires that the patient should take strong drugs to suppress the immune system, as is the case with organ transplants.
To try the efficacy of the stem cell therapy for blinds and to treat the eye disease the researchers injected RPE cells derived from embryonic-stem-cell lines into the eyes of rats. This was a test set up in order to test the efficiency of their proposed solution towards using stem cell therapy for blinds. These rats had a genetic defect in their RPE that causes their vision to slowly deteriorate. The cured animals performed better in vision tests thereby increasing hope that stem cells for blinds when used in humans could prove out to be an effective solution.
