1 Adult stem cells WO2007/130060 A2 Photoreceptor degeneration like AMD, RP etc., night blindness, colour blindness, retinal detachment, ischemic retinopathy, infectious conditions Methods for isolation of adult stem cells from vestigial tissue of a donor suffering from persistent fetal vasculature. The invention further provides procedures to culture these cells to obtain retinal stem cells. The patent also offers a kit for harvesting these extra-retinal ocular tissues to improve survival rate. Pre-clinical Injection or transplantation of retinal stem cells in retinal site, subretinal space, vitreal cavity, optic nerve using a biodegradable carrier [46]
2 Adult stem cells CN102604886 (A) AMD, RP, diabetic retinopathy Human somatic cells are used in the presence of plant extracts and protein inducible autologous retinal stem cells to induce reverse differentiation to yield retinal stem cells having similar markers to retinal cells. - - [47]
