Abstract: This invention provides a method for stably producing type II alveolar epithelial cells from pluripotent stem cells. Specifically, the invention relates to a method for producing type II alveolar epithelial cells from pluripotent stem cells comprising steps of: (1) culturing pluripotent stem cells in a medium containing activin A and a GSK3β inhibitor; (2) culturing the cells obtained in Step (1) in a medium containing a BMP inhibitor and a TGFβ inhibitor; (3) culturing the cells obtained in Step (2) in a medium containing BMP4, retinoic acid, and a GSK3β inhibitor; (4) culturing the ventral anterior foregut cells obtained in Step (3) in a medium containing a GSK3β inhibitor, FGF10, KGF, and a NOTCH signal inhibitor; and (5) subjecting the alveolar epithelial progenitor cells obtained in Step (4) to three-dimensional culture in a medium containing a steroid drug, a cAMP derivative, a phosphodiesterase inhibitor, and KGF.

Abstract: This invention provides a method for stably producing airway epithelial cells from pluripotent stem cells. Specifically, the invention relates to a method for producing airway epithelial cells from pluripotent stem cells comprising steps: (1) culturing pluripotent stem cells in a medium containing activin A and a GSK3β inhibitor; (2) culturing the cells obtained in Step (1) in a medium containing a BMP inhibitor and a TGFβ inhibitor; (3) culturing the cells obtained in Step (2) in a medium containing BMP4, retinoic acid, and a GSK3β inhibitor; (5) subjecting the cells obtained after Step (3) to three-dimensional culture in a medium containing a GSK3β inhibitor, FGF10, and a ROCK inhibitor; and (6) subjecting the proximal airway epithelial progenitor cells obtained in Step (5) to three-dimensional culture in a medium containing a ROCK inhibitor.
