Diabetes mellitus (DM) leads to the development of microvascular diseases and is associated with impaired angiogenesis.The presence of VEGF can block PDGF-BB dependent regulation of neovascularization and vessel normalization.We tested the hypothesis that the inhibition of VEGF improves blood flow in a mouse hindlimb ischemia model.In this study, we examined the effect of bevacizumab, a humanized monoclonal antibody, against VEGF-A, on blood perfusion after hindlimb ischemia.Here, we showed that bevacizumab induces functional blood flow in high fat chow (HFC)-fed diabetic mice.Treatment with bevacizumab increased the expression of PDGF-BB in ischemic muscle, and led to vascular normalization.
