This study aimed to investigate the effects of E26-transformation-specific variant-2 (ETV2) overexpression on wound healing in a cutaneous wound (CW) model and clarify associated mechanisms. pLVX-ETV2 lentivirus expressing ETV2 was constructed and infected into BMSCs to generate ETV2-overexpressed BMSCs (BMSCs+pLVX+ETV2). The RT-PCR assay was applied to amplify ETV2, VE-cadherin, vWF, ARG-1, IL-6, iNOS, TGF-β, IL-10, TNF-α. Western blot was used to determine expression of VE-cadherin and vWF. ETV2 induced differentiation of BMSCs into ECs by increasing CDH5/CD31, triggering tube-like structures, inducing Dil-Ac-LDL positive BMSCs. ETV2 overexpression increased the gene transcription and expression of VE-cadherin and vWF (P<0.01). Transcription of M1 phenotype specific iNOS gene was lower and transcription of M2 phenotype specific ARG-1 gene was higher in the RAW264.7+BMSCs+ETV2 group compared to the RAW264.7+BMSCs+pLVX group (P<0.01). ETV2 overexpression (RAW264.7+BMSCs+ETV2) downregulated IL-6 and TNF-α, and upregulated IL-10 and TGF-β gene transcription compared to RAW264.7+BMSCs+pLVX group (P<0.01). ETV2-overexpressed BMSCs promoted wound healing in CW mice and triggered the migration of BMSCs to the wound region and macrophage activation. ETV2-overexpressed BMSCs promoted collagen fibers and blood vessel formation in the wound region of CW mice. In conclusion, this study revealed a novel biofunction of ETV2 molecule in the wound healing process. ETV2 overexpression in BMSCs promoted wound healing in CW mice by triggering BMSCs differentiation into endothelial cells and modulating the transformation of M1 pro-inflammatory and M2 anti-inflammatory macrophages in vitro and in vivo.
