Induction method of alveolar epithelial progenitor cells

The present invention is stable from pluripotent stem cells and to provide a method of manufacturing the alveolar epithelial progenitor cells, specifically, the pluripotent stem cells, (1) activin A and GSK3β inhibitor culturing in a culture medium containing, (2) culturing in a culture medium containing BMP inhibitors and TGFβ inhibitors, and (3) BMP4, culturing in a culture medium containing retinoic acid, and GSK3β inhibitor including relates to a method for producing the alveolar epithelial progenitor cells.
