|Abstract:||© 2016 Elsevier GmbH. Human mesenchymal stem cell (hMSC) is a potential source for cell therapy due to its property to promote tissue repair. Although, it has been known that hMSCs promote tissue repair via angiogenic cytokines, the interaction between hMSC-derived cytokines and the endothelial progenitor cells (EPCs), which play an important role in tissue neovascularization, is poorly characterized. We investigate the effect of cytokine released from different sources of hMSCs including bone marrow and gestational tissues on the EPC functions in vitro. The migration, extracellular matrix invasion and vessel formation of EPCs were studied in the presence or absence of cytokines released from various sources of hMSCs using transwell culture system. The migration of EPCs was highest when co-culture with secretory factors from placenta-derived hMSCs (PL-hMSCs) compared to those co-culture with other sources of hMSCs. For invasion and vessel formation, secretory factors from bone marrow-derived hMSCs (BM-hMSCs) could produce the maximal enhancement compared to other sources. We further identified the secreted cytokines and found that the migratory-enhancing cytokine from PL-hMSCs was PDGF-BB while the enhancing cytokine from BM-hMSCs on invasion was IGF-1. For vessel formation, the cytokines released from BM-hMSCs were IGF1 and SDF-1. In conclusion, hMSCs can release angiogenic cytokines which increase the migration, invasion and vessel forming capacity of EPCs. We can then use hMSCs as a source of angiogenic cytokines to induce neovascularization in injured/ischemic tissues.|
