[Research progress of mesenchymal stem cells in the treatment of ALI]

Acute lung injury (ALI) is one of the most common clinical critical illnesses. Its severe stage is acute respiratory distress syndrome (ARDS), characterized by rapid onset and high mortality. There is no effective treatment. Based on many preclinical studies, mesenchymal stem cells (MSCs) have great potential as a therapeutic strategy for ALI, clinical trials are underway, and studies on the therapeutic effects of MSCs progressively deep into the molecular mechanism and continue to make new progress. However, the use of MSCs, their specific methods and risks, especially on the risk of iatrogenic tumor formation remains unresolved. In this paper, we reviewed the main problems in the application of MSCs in the treatment of ALI and the main problems in the application of MSCs in order to explore the feasibility and future direction of MSCs in the treatment of ALI.
