[Microvesicles derived from mesenchymal stem cells: new hope of the treatment for ARDS].

OBJECTIVE: Acute respiratory distress syndrome (ARDS) is a serious state threaten human health with a high mortality about 30%-40%. At present, there is no effective treatment for ARDS. Microvesicles derived from mesenchymal stem cells (MSC-MVs) have a heterogeneous subcellular structure secreted by MSCs. It plays an important role in the repair of tissue and organ damage. Recent studies have shown that MSC-MVs, played an important role in repairing lung injury, may replace MSC for cell therapy. Therefore MSC-MVs may bring new hope for ARDS treatment.
