Vascularisation

Vascularisation or neovascularization (neo- + vascular + -ization) is the physiological process through which blood vessels form in tissues or organs.

Growth factors that inhibit neovascularization include those that affect endothelial cell division and differentiation. These growth factors often act in a paracrine or autocrine fashion; they include fibroblast growth factor, placental growth factor, insulin-like growth factor, hepatocyte growth factor, and platelet-derived endothelial growth factor.

It may occur through angiogenesis (the formation of new blood vessels form from pre-existing ones), vasculogenesis (the creation of blood vessels during development, particularly in embryos) or arteriogenesis (where smaller vessels become enlarged into fully functioning arteries).
