In this setting, the patient derived iPSCs were differentiated into a monolayer of retinal pigment epithelial cells and further transplanted into the affected retina. Several preceding in vitro studies as well as the approval of the method in animal models had been performed [41–43]. The targeted time-frame of this study will last approximately 10 months with a follow-up study of four years. More clinical trial will and should follow in this promising field of research.
