Abstract

The formation of new vessels is a complex problem. In this process the key role is played by the vascular-endothelial growth factor (VEGF). It is secreted, among others, by macrophages and endothelial cells. Genes for VEGF are located on the sixth chromosome. Hypoxia is a mandatory signal for the start of the angiogenesis process. Activated through hypoxia, HIF proteins move to the cells nucleus and regulate expression of vascular-endothelial growth factor. VEGF through its receptors on endothelial cells leads to the proliferation of new vessels.
