Abstract:
Idiopathic pulmonary fibrosis (IPF) is an irreversible and highly mortal interstitial disease. The incidence of IPF is increasing around the world, which seriously harms human health and brings huge economic burden to the society. While traditional treatments can slow the progression of the disease, they are far to cure this disease. Clinically, pirfenidone and nintedanib are two main drugs that used for the treatment of IPF. However, severe adverse reactions were reported in some patients. Therefore, it is very important to explore novel therapeutic strategies to reverse fibrosis and regenerate lung. The repair and regeneration ability of stem cells has unique advantages in the treatment of pulmonary fibrosis. The structure and function of organoids produced by stem cells have similar characteristics with live organs. Therefore, lung stem cells play an important role in the discovery of novel anti-IPF drugs, and in the formation and development of lung tissue. In addition, organoids produced by stem cells also serve as a perfect model for regenerative medicine. In this review, we mainly summarize the role of stem cells and organoids in the repair and regeneration of pulmonary fibrosis, and hope to provide a reference for the development of clinical treatment of pulmonary fibrosis.
