Chronic obstructive pulmonary disease(COPD)is a heterogeneous lung condition characterized by persistent airflow obstruction caused by long-term airway inflammation or alveolar abnormalities,often manifested as chronic respiratory symptoms and decreased lung function.In recent years,experimental research has shown that mesenchymal stem cells(MSC)have anti-inflammatory,immunomodulatory,and repairing properties of lung epithelial cells,which can be used to treat various diseases including COPD.This article is mainly based on the main findings of in vitro and in vivo animal model experiments and clinical studies of MSC treatment for COPD.It summarizes and discusses the possible mechanisms of action of MSC as a new therapy,and provides new ideas for clinical treatment of COPD.
