Tumor vasculogenesis is a complex process driven by the VEGF, PDGF, EGF, FGF, and ANG families, with VEGF-VEGFR and FGF2-FGFR1/2 signaling playing key roles by promoting endothelial cell proliferation and migration, duct formation, and protease production [18, 144–146]. The gene discussed is FGF2; the disease is neoplasm.
