Mesenchymal Stem Cell-Derived Exosomes in Cardioprotection: A Novel Application to Prevent Myocardial Injury.

Perioperative myocardial injury is a common complication caused by major surgery. Many pharmacological and nonpharmacological studies have investigated perioperative cardioprotection. However, the methods are insufficient to meet the increasing clinical needs for cardioprotection. The application of Mesenchymal Stem Cell-Derived Exosomes (MSC-Exos) is a novel cell-free therapeutic strategy and has significantly benefitted patients suffering from various diseases. In this review, we comprehensively analyzed the application of MSC-Exos to prevent myocardial infarction/injury by regulating inflammatory reactions, inhibiting cardiomyocyte apoptosis and autophagy, promoting angiogenesis, and mediating cardiac remodeling. Finally, we assessed the therapeutic effects and the challenges associated with the application of MSC-Exos from a clinical perspective.
