How does vegf cause angiogenesis
WebA key role in angiogenesis is played by vascular endothelial growth factor (VEGF). The regulation of blood vessel growth to match the needs of the tissue depends on the control of VEGF production through changes in the stability of its mRNA and in its rate of transcription. WebVEGF is a powerful angiogenic agent in neoplastic tissues, as well as in normal tissues. Under the influence of certain cytokines and other growth factors, the VEGF family appears in cancerous tissue and the adjacent stroma, and plays an important role in neovascularization (Folkman 1990, 1995a, 1995b).
