[Application Prospect of Stem Cell-derived Microvesicles in Regeneration of Injured Tissues]
Abstract:
More and more evidence indicates that microvesicles (MVs) play a key role in cell-to-cell communication. The MVs are circular fragments of membrane released from the endosomal compartment as exosomes or shed from the cell surface membranes of most types. Components of donor cells are incorporated into MVs that contain bioactive lipids, proteins, genetic cargoes. MVs derived from stem cells may reprogram cells that survived in injury tissue and favor tissue regeneration by delivering their bioactive cargoes to influence the behaviors of recipient cells. Compared with mesenchymal stem cells (MSCs), MVs derived from MSCs were found to mimic the beneficial effects of these cells. These proregenerative effects mediated by MVs can be explained by the fact that MVs are enriched in bioactive lipids, anti-apoptotic and pro-stimulatory growth factors or cytokines, and deliver mRNAs, regulatory miRNAs and proteins that improve overall cell function. Therefore, it opens novel perspectives in exploiting these MVs in tissue regeneration and repair. In addition, the use of MVs instead of stem cells could represent a safe and potentially more advantageous alternative to cell-therapy approaches.
