Lung organoids have been produced from human pluripotent stem (iPS) cells that contain various components of lung tissue, and even airways and alveolar structures (see HERE). Recapitulation of lung development from human pluripotent stem cells (hPSCs) in three dimensions (3D) would allow deeper insight into human development, as well as the development of innovative strategies for disease modelling, drug discovery and regenerative medicine. Lung organoids produced resemble those of the second trimester of pregnancy. The authors discuss the potential use of this model to study pulmonary fibrosis in vitro and to model lung diseases.
