Abstract
Progressive photoreceptor loss in retinal degenerative diseases leads to irreversible vision impairment. Transplantation of human embryonic or induced pluripotent stem cell-derived photoreceptor precursor cells (PRPCs) offers potential for vision restoration. However, substantial early donor cell loss remains a major challenge. This study aims to elucidate the mechanisms underlying early PRPC loss and to evaluate host retinal responses to transplantation.
