ENDODERMAL CELL MASS, AND METHOD FOR PRODUCING ANY ONE OF THREE PRIMARY GERM LAYER CELL MASS FROM PLURIPOTENT CELLS

摘要

The present invention addresses the problem of providing an endodermal cell mass for producing somatic cells that are best as a cell therapy preparation. The endodermal cell mass according to the present invention is a cell mass in which the content of undifferentiated cells is reduced and which contains endodermal cells capable of being differentiated into somatic cells that are best as a cell therapy preparation. Somatic cells derived from the endodermal cell mass of the present invention have an excellent therapeutic effect as a cell therapy preparation.
