Retinal progenitor cells: Targeting retinitis pigmentosa: For visual recovery to occur, there must be photoreceptors left that can be rescued.

The article discusses a study reported by Dr. Henry Klassen in a presentation at the 8th annual Retinal Cell and Gene Therapy Innovation Summit in New Orleans, Louisiana, where he explained that retinal progenitor cells (RPCs) supply neurotrophic factors (NTFs) that in turn support survival and function of retinal neurons. Topics discussed include remarks by Klassen on substantial interocular differences in best-corrected visual acuities (BCVAs) and finding on the retinal anatomy.
