communication. In recent years, several in vitro and in vivo studies have demonstrated that
notch-signalling functions as a negative feedback mechanism downstream of the VEGF-
signalling pathway that acts to finely shape the vascular network. Notch activation by the
Jagged-1 and Delta-like 4 ligands regulates different steps of blood vessel development
ranging from proliferation and survival of endothelial cells, to vessel branching and arterial …
