Fig. 5From: Experimental study of the effects of hypoxia simulator on osteointegration of titanium prosthesis in osteoporotic ratsDeferoxamine (DFO) activated the HIF-1a signaling pathway under normoxic conditions, which could significantly increase the mRNA expression levels of VEGF, thereby further improving the mRNA expression levels of CD31. A The mRNA expression levels of VEGF in both groups. B The mRNA expression levels of CD31 in both groups. An asterisk (*) indicates p < 0.05Back to article page
