The present invention relates to a differentiation inducing method comprising: introducing, into human induced pluripotent stem cells, a combination of genes of transcription factors which are possessed by fetal and adult hepatic cells, but are not possessed by human induced pluripotent stem cells; and adhering the human induced pluripotent stem cells to a substrate for monolayer culture in a medium containing a combination of growth-promoting agents for proliferation and differentiation, thereby enabling induction of the differentiation of the human induced pluripotent stem cells in large amounts in a short term, a hepatic progenitor cell produced by the method, and a cell composition for transplantation into the liver comprising the cell. The transcription factors include FOXA2, GATA4, HEX and C/EBPα, and the growth-promoting agents include oncostatin M, an epidermal growth factor, retinoic acid, dexamethasone, insulin, transferrin and a selenite ion.
A method of inducing the differentiation of an undifferentiated human pluripotent stem cell to obtain a hepatic progenitor cell, comprising a step of expressing a combination of transcription factors for differentiation induction in the human pluripotent stem cell which is adhered to a substrate for monolayer culture in a medium for differentiation.
A method of inducing the differentiation of human induced pluripotent stem cell (human iPS cell) to obtain a human hepatic progenitor cell, comprising steps of:
A human hepatic progenitor cell obtained by inducing the differentiation of a human induced pluripotent stem cell (human iPS cell), wherein
