Angiogenesie and vasculogenesis comprise the mechanisms that responsible for the development of new blood vessels. Vasculogenesis is the process of in situ formation of blood vessels from endothelial progenitor cells or angioblast. Angiogenesis involves extension of the already formed primitive vasculature by the sprouting of new capillaries through migration and proliferation of previously differentiated ECs.
