PLURIPOTENT STEM CELL CAPABLE OF BEING ISOLATED FROM FAT TISSUE OR UMBILICAL CORD OF BIOLOGICAL BODY

摘要

The present invention provides a method for directly obtaining a pluripotent stem cell from the fat tissue or the umbilical cord of a biological body, and the pluripotent stem cell obtained by means of the aforementioned method. A SSEA-3 positive and CD105 positive pluripotent stem cell which is capable of being isolated from the fat tissue or the umbilical cord of a biological body by using the expression of SSEA-3 as an index and which has all of the following properties: (i) has little or no telomerase activity; (ii) is capable of differentiating into any of the triploblastic cells; (iii) does not exhibit neoplastic propagation; and (iv) exerts replication competence (self-renewal abilities).
