Human iPSC-derived Retinal Pigment Epithelials


Human iPSC-derived Retinal Pigment Epithelials

Retinal pigment epithelium (RPE) is the pigmented cell layer surrounding the neurosensory retina. The cells support the retinal photoreceptor cells, and they are attached to the underlying choroid and overlying retinal visual cells. The RPE has several functions: light absorption, epithelial transport, spatial ion buffering, visual cycle, phagocytosis, secretion and immune modulation.  The RPE is comprised of hexagonal cells organized into a densely packed monolayer. The RPE is of the neuroectodermal origin.

Tempo-iRPE™ are human iPSC-derived retinal pigment epithelial cells. They express biomarkers (e.g., RPE-65, RLBP1, and BEST). They grow as a monolayer and show abilities to phagocytose. The iRPEs play a critical role in functionally support the photoreceptors. They are valuable tools for studying age-related macular degeneration, retinitis pigmentosa, diabetic retinopathy, photoreceptor degeneration, gene expression, phagocytosis, and cellular interactions.
