Mesenchymal Stromal Cell Exosomes in Cardiac Repair

Curr Cardiol Rep. 2022 Apr;24(4):405-417. doi: 10.1007/s11886-022-01660-1. Epub 2022 Jan 29.

Abstract

Purpose of the review: Mesenchymal stromal cells (MSCs) are considered an attractive option for cell-based therapy because of their immune-privileged phenotype and paracrine activity. Substantial preclinical evidence indicates that MSC exosomes recapitulate MSC cellular function in cardiac regeneration and repair. Therefore, in this review, we briefly discuss the latest research progress of MSC exosomes in cardiac repair and regeneration.

Recent findings: The recent revolutionary advance in controlling the contents of the exosomes by manipulating parental cells through bioengineering methods to alter specific signaling pathways in ischemic myocardium has proven to be beneficial in the treatment of heart failure. MSC Exosomes appear to be leading candidates to treat myocardial infarction and subsequent heart failure by carrying rich cargo from their parental cells. However, more clinical and pre-clinical studies on MSC exosomes will be required to confirm the beneficial effect to treat cardiovascular diseases.

Keywords: Angiogenesis; Cardiac fibrosis; Exosomes; Inflammation; Mesenchymal stromal cells.
