Alveolar epithelial type II (AT2) cells secrete pulmonary surfactant via lamellar bodies (LBs). Abnormalities in LBs are associated with disorders, including fibrosis. However, high-content screening (HCS) for LB abnormalities is limited by the lack of understanding AT2 cell functions. In present study, we have developed harboring LB-like organelles that proteins. These were more similar to tha...
