Abstract: Extracellular vesicles (EVs), which are released by most of the cells,
constitute a new system of cell-cell communication by transporting DNA, RNA, and
proteins in various vesicles namely exosomes, apoptotic bodies, protein complexes,
high-density lipid (HDL) microvesicles, among others. To ensure accurate regulation of
somatic stem cell activity, EVs function as an independent metabolic unit mediating the
metabolic homeostasis and pathophysiological of several diseases such as
cardiovascular diseases, metabolic diseases, neurodegenerative diseases, immune
diseases, and cancer. Whist examining the EV biomolecules cargos and their
microenvironments that lead to epigenetic alteration of the cell in tissue regeneration,
studies have gained further insights into the biogenesis of EVs and their potential roles
in cell biology and pathogenicity. Due to their small size, non-virulence, flexibility, and
ability to cross biological barriers, EVs have promising therapeutic potentials in various
diseases. In this review, we describe EV’s mechanism of action in intercellular
communication and transfer of biological information as well as some details about EVinduced
epigenetic changes in recipient cells that cause phenotypic alteration during
tissue regeneration. We also highlight some of the therapeutic potentials of EVs in
organ-specific regeneration.
