This article shows that laminin α4, Lama4, regulates tip cell (leading endothelial cells during angiogenesis) numbers and vascular density by inducing endothelial Dll4/Notch signalling in vivo. Appropriate laminin/integrin-induced signalling is necessary to regulate branching frequency during sprouting angiogenesis.
