TECHNIQUE FOR ISOLATING/CULTURING COLORECTAL EPITHELIAL STEM CELL, AND TECHNIQUE FOR TRANSPLANTING COLORECTAL EPITHELIUM EMPLOYING SAID TECHNIQUE

摘要

The purpose of the present invention is to provide: a culture medium for the in vitro culture of a colorectal epithelial stem cell or the like; a method for culturing a colorectal epithelial stem cell or the like in vitro using the culture medium; a prophylactic/therapeutic agent for bowel diseases, which comprises a colorectal epithelial stem cell or the like produced by culturing by the aforementioned method; a method for administering, i.e., transplanting, a colorectal epithelial stem cell or the like produced by culturing by the aforementioned method to a patient suffering from a bowel disease; and a method for isolating a colorectal epithelial stem cell or the like. The culture medium, the prophylactic/therapeutic agent and the methods are characterized by using a culture medium for the in vitro culture of a colorectal epithelial stem cell and/or a colorectal epithelial cell, which comprises serum albumin, Wnt3a and r-spondin-1.
