Promigratory and proangiogenic effects of AdipoRon on bone marrow-derived mesenchymal stem cells: an in vitro study.

ObjectivesTo investigate the effect of AdipoRon on major factors involved in survival, migration and neovascularization of rat bone marrow-derived mesenchymal stem cells.ResultsAdipoRon promoted the MSCs viability. Real-time PCR indicated that the expression of cyclooxygenase-2 (COX-2), hypoxia-inducible factor-1 (HIF-1) C-X-C chemokine receptor type 4 (CXCR4), C-C chemokine receptor type 2 (CCR2), vascular endothelial growth factor matrix metalloproteinase-2 (MMP-2) and MMP-9 were upregulated in AdipoRon-treated MSCs compared to control groups. Prostaglandin E2 (PGE2) level, as well as migration ability of MSCs (scratch assay) was enhanced by AdipoRon preconditioning.ConclusionPreconditioning of MSCs with AdipoRon prior to transplantation could enhance cell survival, angiogenesis and migration via activating the COX-2/PGE2/HIF-1 pathway and other contributing factors.
