Preservation of Retinal Anatomy and Synaptic Connectivity Following Preventive Subretinal Injections of Human RPE Cells in the Royal College of Surgeons (RCS) Rat

I. Pinilla, Y. Sauvé, N. Cuenca, E. Abecia, R. D. Lund Purpose: To examine the effect of preventive subretinal cell injections in the RCS rat on the outer retina and synaptic connectivity between photoreceptors and their target neurons. Methods: Eight rats received subretinal injections of a human RPE cell line (ARPE19) at age P22; they were sacrificed at P90 (n=4) and P120 (n=4). Controls consisted of 6 unoperated rats sacrificed at the...
