VEGFA and neoplasm: Some of the angiogenic factors involved in tumor-induced angiogenesis include vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), fibroblast growth factor (FGF), and cytokines such as interleukins (ILs), tumor necrosis factors (TNFs), interferons (INFs), and tumor growth factors (TGFs) [14].
