Vascular endothelial growth factor A is a member of VEGF family and acts with its receptor in tumor angiogenesis, a very complex phenomenon that passes through several steps including the disrupture of the basal membrane, the increase in proliferation of endothelial cells, the interaction between cells and the matrix, and the mobilization of endothelial cells and hematopoietic progenitors [92]. Here, VEGFA is linked to neoplasm.
