Fig. 3From: Umbilical cord-matrix stem cells induce the functional restoration of vascular endothelial cells and enhance skin wound healing in diabetic mice via the polarized macrophagesUCMSCs regulate the local inflammatory microenvironments of the wound bed tissues. Relative gene expression levels of several cytokines in the wound bed tissue at day 3 post treatment were quantified by real-time PCR. a IL-1β. b TGF-β. c TNF-α. d IL-6. e IL-10. f VEGF. n = 6 per group. *P < 0.05, **P < 0.01Back to article page
