cells can differentiate into
retinal pigment epithelium or photoreceptor
cells, which play a critical role in macular degeneration.
Cell therapy, as envisaged by the teams of I - Stem, is primarily based on the identification of experimental protocols that can specifically guide differentiation of pluripotent cells to a cell fate, which presents a interest for the replacement of the defective cell population from the patient (the striatal neurons for Huntington's disease, the cells of the retinal pigment epithelium for retinitis pigmentosa, keratinocytes for genodermatoses, et
