The in vitro generation of lung and airway progenitor cells from human pluripotent stem cells.

ABSTRACT: Lung and airway epithelial cells generated in vitro from human pluripotent stem cells (hPSCs) have applications in regenerative medicine, modeling of lung disease, drug screening and studies of human lung development. Here we describe a strategy for directed differentiation of hPSCs into developmental lung progenitors, and their subsequent differentiation into predominantly distal lung epithelial cells. The protocol entails four stages that recapitulate lung development, and it takes ∼50 d. First, definitive endoderm (DE) is induced in the presence of high concentrations of activin A. Subsequently, lung-biased anterior foregut endoderm (AFE) is specified by sequential inhibition of bone morphogenetic protein (BMP), transforming growth factor-β (TGF-β) and Wnt signaling. AFE is then ventral
