Mammalian extraembryonic endoderm cells and methods of isolation

摘要

An isolated mammalian extraembryonic endoderm-like cell line is provided. Methods for producing isolated mammalian extraembryonic endoderm-like cell line derived from a mammalian pluripotent stem cell culture are provided. Primate or human embryonic stem cells (ESCs) spontaneously generate the primate or human extraembryonic endoderm-like cell line wherein the extraembryonic endoderm-like cells sustain the pluripotence of the primate or human ESCs.
