METHODS OF MAMMALIAN RETINAL STEM CELL PRODUCTION AND APPLICATIONS

摘要

The invention provides an in vitro method for producing isolated mammalian primitive retinal stem cells (pRSCs) comprising: (a) culturing isolated embryonic stem cells (ESCs) from a mammal in a cell culture medium that is free of feeder cells, feeder-conditioned medium or serum so as to produce and grow a culture of the isolated ESCs; and (b) contacting the culture of the isolated ESCs so grown with one or more of an inhibitor for Wnt or TGF-β/BMP signaling so as to differentiate the isolated ESCs of (a) into primitive retinal stem cells thereby producing isolated mammalian pRSCs.
