The alveolar epithelium is composed of two cell types: type I cells comprise 95% of the gas exchange surface area, whereas type II cells secrete surfactant, while retaining the ability to convert into type I cells to induce alveolar repair. Using lineage-tracing analyses in the mouse model of Pseudomonas aeruginosa-induced lung injury, we identified a population of stem cell antigen (Sca)-1-expressing type II cells with progenitor cell properties that mediate alveolar repair. These cells were sh ...[more]
