Transplanted human induced pluripotent stem cells- derived retinal ganglion cells embed within mouse retinas and are electrophysiologically functional.

ABSTRACT: Glaucoma is an optic neuropathy characterized by permanent visual field loss caused by the death of retinal ganglion cells (RGCs) and it is the leading cause of irreversible blindness worldwide. Consequently, there is an unmet need for the development of new strategies for its treatment. We investigated RGC replacement therapy as a treatment for ganglion cell loss. Human-induced pluripotent stem cells (hiPSCs) were differentiated into mature, functional RGCs in vitro, labeled with AAV2.7m8-SNCG-eGFP, and transplanted intravitreally in wild-type 4-month-old C57BL/6J mice. Survival of the transplanted hiPSC-RGCs was assessed by color fundus photography and histological studies confirmed the localization of the transplanted hiPSC-RGCs within the retina.
