MSC-based therapies for pre-clinical studies in lung diseases. MSCs can be obtained from most human tissues, including bone marrow (BM), adipose tissue (AD), umbilical cord (UC), Wharton’s jelly (WJ), menstrual blood, placenta, dental pulp, and lung. MSCs can treat many lung diseases, such as acute lung injury, idiopathic pulmonary fibrosis (IPF), acute respiratory distress syndrome (ARDS), lung cancer, asthma, and chronic obstructive pulmonary disease (COPD)
