Fig. 6From: A dual role of HIF1α in regulating osteogenesis–angiogenesis couplingHIF1α facilitated the indirect angiogenic ability of ABMSCs and inhibited that of YBMSCs. A, C–G, H, J–N Wound healing assay, transwell assay and tube formation assay of HUVECs after 24-h CM-BMSCs treatment. Bar = 100 μM. B, I Concentration of VEGF-A in different groups by Elisa. CM, conditional medium collected from BMSCs. *p < 0.05 versus YBMSC-NC or YBMSC-pCMV-blank; #p < 0.05 versus ABMSC-NC or ABMSC- pCMV-blankBack to article page
