An object of the present invention is to provide a new means capable of easily and efficiently preparing cells showing a function more similar to the function of intestinal epithelial cells of a living body. According to the present invention, pluripotent stem cells are induced to differentiate into intestinal stem cell-like cells by a method for inducing differentiation of pluripotent stem cells into intestinal epithelial cells, the method including a step (1) of differentiating pluripotent stem, cells into intestinal stem cell-like cells and a step (2) of differentiating the intestinal stem cell-like cells obtained in the step (1) into intestinal epithelial cell-like cells by using an MEK1 inhibitor, a DNA methylation inhibitor, a TGFβ receptor inhibitor, EGF, and a cAMP activator in combination.

Method for inducing differentiation of pluripotent stem cells into intestinal epithelial cells

An object of the present invention is to provide a novel method which enables convenient preparation of cells exhibiting functions close to that of intestinal epithelial cells of living bodies, and use of the method. The differentiation of induced pluripotent stem cells into intestinal epithelial cells is induced by step of differentiating induced pluripotent stem cells into endoderm-like cells; step of differentiating the endoderm-like cells obtained in step into intestinal stem cell-like cells; and step of differentiating the intestinal stem cell-like cells obtained in step into intestinal epithelial cell-like cells, wherein step includes culture in the presence of a MEK1 inhibitor, a DNA methyltransferase inhibitor, a TGF-&#x3b2; receptor inhibitor, and EGF and under the condition that cAMP is supplied to the cells.
