This article is from European Journal of Histochemistry : EJH, volume 58.AbstractAngiogenesis is a process of development and growth of new capillary blood vessels from pre-existing vessels. Angiogenic growth factors play important roles in the development and maintenance of some malignancies, of which vascular endothelial growth factor VEGF-VEGFR2 interactions are involved in proliferation, migration, and survival of many cancer cells. The aim of this study was to investigate the function of VEGFR2 in human hemangiomas HAs. Using immunohistochemistry assay, we examined the expression levels of VEGF, VEGFR2, Ki-67, glucose transporter-1 Glut-1, phosphorylated protein kinase B p-AKT and p-ERK in different phases of human HAs. Positive expression of VEGF, VEGFR2, Ki-67, Glut-1, p-AKT and p-ERK was significantly increased in proliferating phase HAs, while decreased in involuting phase HAs P=0.001; P=0.003. In contrast, cell apoptotic indexes were decreased in proliferating phase HAs, but increased in involuting phase HAs P
