Research Abstract

We investigated the formation of venous angles that the physiology connection site between blood vessels and lymphatic vessels. Also we analyzed the abnormal blood-lymph connection in Plcg2^<-/-> mice. Valves in venous angle were consist with blood endothelial cells and lymphatic endothelial cells(LECs) two layers cells. We detected the abnormal blood-lymph connection were randomly present in Plcg2^<-/-> and LEC extends filopodia to blood vessels at connection site. In addition, platelets inhibit proliferation and migration of LECs. Taken together, We proposed new molecular mechanisms : During lymphatic development, Platelets regulate the separation between blood and lymphatic vessel by inhibiting of proliferation and migration, inducing of retraction of lymphatic endothelial cells which encounter to blood vessels during lymphatic sprouting in the peripheral tissue.
