Recent literature suggests that extracellular vesicles (EVs), secreted from most cells and containing cell-specific cargo of proteins, lipids, and nucleic acids, are major driver of intracellular communication in normal physiology and pathological conditions. The recent evidence on stem/progenitor cell EVs as potential therapeutic modality mimicking their parental cell function is exciting because EVs could possibly be used as a surrogate for the stem cell-based therapy, and this regimen may overcome certain roadblocks identified with the use of stem/progenitor cell themselves. This review provides a comprehensive update on our understanding on the role of EVs in cardiac repair and emphasizes the applications of stem/progenitor cell-derived EVs as therapeutics and discusses the current challenges associated with the EV therapy.
