Patent ID: 10377991

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.
