Abstract:
The present invention provides a production method of a retinal pigment epithelial cell containing the following steps:
(1) a first step for culturing a pluripotent stem cell in a medium containing at least one kind selected from the group consisting of an FGF receptor inhibitor and an MEK inhibitor for a period of not more than 30 days, and
(2) a second step for culturing the cell obtained in the first step in a medium containing at least one kind selected from the group consisting of a Rho signal transduction pathway inhibitor and an apoptosis inhibitor to form a retinal pigment epithelial cell. The method can produce retinal pigment epithelial cells from pluripotent stem cells more efficiently and conveniently.
