TY - EJOU AU - Ferrara, Napoleone TI - VEGF-A: a critical regulator of blood vessel growth T2 - European Cytokine Network PY - 2009 VL - 20 IS - 4 SN - 1952-4005 AB - Angiogenesis is required for a variety of normal and pathological, proliferative processes. Numer-ous regulators of angiogenesis have been identified and characterized over the last decades. Among these, vas-cular endothelial growth factor (VEGF)-A appears especially important in normal development and in disease processes. Several VEGF inhibitors have been approved by the FDA for the treatment of tumors or the neovas-cular form of age-related macular degeneration. This article examines the molecular and biological characteris-tics of VEGF and also discusses preclinical and clinical studies with VEGF inhibitors and the lessons learned from these studies.
