Subretinal Transplantation of MACS Purified Photoreceptor Precursor Cells into the Adult Mouse Retina

Overview

This study presents a method for transplanting enriched photoreceptor precursor cells into the retina of recipient mice. The approach aims to facilitate the integration of these cells into the host retina, potentially aiding in the restoration of vision.
