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

Abstract

Objectives: To investigate the effect of AdipoRon on major factors involved in survival, migration and neovascularization of rat bone marrow-derived mesenchymal stem cells. Results: AdipoRon 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. Conclusion: Preconditioning 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.
