title: Transplantation to the diseased and damaged retina.
abstract: Retinas of Royal College of Surgeons (RCS) dystrophic rats undergo a dramatic loss of photoreceptor cells as a result of defective retinal pigment epithelial (RPE) cells. These retinas are therefore a valuable model in the investigation of the role of the RPE on photoreceptor-cell survival and development. Also, rat retinas damaged by excessive light serve as a suitable environment to study survival of transplanted photoreceptor cells. Even though photoreceptor cells are lost in these retinas, a normal inner retinal structure is retained. Both models have recently been used in successful RPE-cell and/or photoreceptor-cell transplantation studies designed to replace defective or lost cells due to retinal disease or damage. These new approaches in the field of retinal transplantation offer unique and novel opportunities for the development of possible therapeutic strategies in human eye disease, and for improving our understanding of the normal relationships between retinal cells.
