They recapitulate cell-cell, cell-niche interactions in tissue development, homeostasis, regeneration anddisease, and provide an in vitro model for drug screening. This review summarizes the recent advances of organoidcultures derived from adult lung stem cells and human pluripotent stem cells, especially focusing on the organoidsof the distal airway stem/progenitor cells. We also discuss the applications of organoids in studying lungregeneration and pulmonary diseases, including pulmonary fibrosis, airway diseases and Coronavirus disease 2019(COVID-19).展开更多
