摘要:
The present invention provides: [1] a method for producing a retinal tissue, characterized by comprising steps (1) to (3), i.e., (1) a first step of subjecting a pluripotent stem cell to floating culture in a serum-free culture medium containing a Wnt signaling pathway inhibitor to form an aggregate of the pluripotent stem cell, (2) a second step of subjecting the aggregate formed in the first step to floating culture in a serum-free culture medium containing a basement membrane preparation, and (3) a third step of subjecting the aggregate cultured in the second step to floating culture in a serum-containing culture medium; [2] a method for producing an optic-cup-like structure, characterized by comprising a step of subjecting the aggregate containing a retinal tissue which has been cultured in the third step mentioned above to floating culture in a serum-free culture medium or a serum-containing culture medium each containing a substance capable of acting on the Sonic hedgehog signaling way and a substance capable of acting on the Wnt signaling pathway; [3] a method for producing a retinal pigment epithelial cell, characterized by comprising a step of subjecting the aggregate containing a retinal tissue which has been cultured in the third step mentioned above to floating culture in a serum-free culture medium or a serum-containing culture medium each containing a substance capable of acting on the Wnt signaling pathway (wherein the serum-free culture medium and the serum-containing culture medium does not contain any substance capable of acting on the Sonic hedgehog signaling pathway); and [4] a method for producing a retinal-layer-specific nerve cell, characterized by comprising bringing a retinal progenitor cell contained in a retinal tissue derived from a primate pluripotent stem cell into contact with a Notch signaling pathway inhibitor.
