Obtaining alveolar epithelial type 2 cells (AEC2s) from human pluripotent stem cells (hPSCs) offers great scientific and clinical promise. In this issue of Cell Stem Cell, Jacob et al. (2017) report a method for the directed differentiation of hPSCs into mature AEC2s and demonstrate its application in modeling alveolar lung diseases.
