The present invention provides a method for producing a retinal progenitor 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, and (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 but containing a substance acting on the BMP signal transduction pathway, thereby obtaining an aggregate containing retinal progenitor cells.

A method for making an at least double layered cell aggregate and/or an artificial blastocyst, and/or a further-developed blastoid termed blastoid, by forming a double layered cell aggregate from at least one trophoblast cell and at least one pluripotent and/or totipotent cell, and culturing the aggregate to obtain an artificial blastocyst having a trophectoderm-like tissue that surrounds a blastocoel and an inner cell mass-like tissue. The cell aggregate can be formed from toti- or pluripotent stem cell types, or induced pluripotent stem cell types, in combination with trophoblast stem cells. Formation of a blastoid can be achieved by culturing the cell aggregate in a medium preferably comprising one or more of a Rho/ROCK inhibitor, a Wnt pathway modulator, a PKA pathway modulator, a PKC pathway modulator, a MAPK pathway modulator, a STAT pathway modulator, an Akt pathway modulator, a Tgf pathway modulator and a Hippo pathway modulator.
