摘要:
The present invention providesa method for producing a retinal pigment epithelial cell, including(1) a first step of subjecting pluripotent stem cells to floating culture in a serum-free medium to form an aggregate of pluripotent stem cells,(2) a second step of subjecting the aggregate formed in step (1) to floating culture in a serum-free medium or serum-containing medium each being free of a substance acting on the Sonic hedgehog signal transduction pathway and containing a substance acting on the BMP signal transduction pathway, thereby obtaining an aggregate containing retinal progenitor cells, and(3) a third step of subjecting the aggregate formed in step (2) to floating culture in a serum-free medium or serum-containing medium each being free of a substance acting on the Sonic hedgehog signal transduction pathway and a substance acting on the BMP signal transduction pathway and containing a substance acting on the Wnt signal pathway, thereby obtaining an aggregate containing retinal pigment epithelial cell.
