| 摘要 |
The present invention relates to a method for inducing the differentiation of mammals' embryonic stem cells into keratinocytes, comprising the following steps of: isolating an extracellular matrix secreted by at least one mammals' cell type, cultivating mammals' embryonic stem cells in parallel in an undifferentiated condition in an appropriate culture medium in the presence of LIF, seeding the embryonic stem cells as a monolayer on said extracellular matrix, cultivating the thus seeded embryonic stem cells in the absence of LIF for a period of time sufficient for their differentiation into keratinocytes, and collecting the thus obtained keratinocytes.
