PURPOSE To characterize the potential of newborn retinal stem cells (RSCs) isolated from the radial glia population to integrate the retina, this study was conducted to investigate the fate of in vitro expanded RSCs transplanted into retinas devoid of photoreceptors (adult rd1 and old VPP mice and rhodopsin-mutated transgenic mice) or partially degenerated(More)
The purpose of the present work was to generate, from retinal stem cells (RSCs), a large number of cells committed toward the photoreceptor fate in order to provide an unlimited cell source for neurogenesis and transplantation studies. We expanded RSCs (at least 34 passages) sharing characteristics of radial glial cells and primed the cells in vitro with(More)
Cell transplantation is an active field of research to replace lost cells in retinal dystrophies to potentially restore visual function. We hypothesized that in-vitro differentiated retinal stem cells would integrate the appropriate retinal layer and differentiate into photoreceptors when transplanted during development. Here we show that retinal stem cells(More)
PURPOSE C57/Bl6, Cpfl1(-/-) (cone photoreceptors function loss 1; pure rod function), Gnat1a(-/-) (rod α-transducin; pure cone function), and Rpe65(-/-);Rho(-/-) double-knockout mice were studied to distinguish the respective contributions of the different photoreceptor (PR) systems that enable light perception and mediate a visual reflex in adult(More)
