血管内皮细胞 (VEC)为衬贴在血管腔表面的单层扁平细胞。近年的研究表明它不仅起屏障作用 ,还具有重要的内分泌功能 ,参与血管损伤的修复和免疫反应 ,被人们称为体内最大的内分泌和旁分泌器官。由于VEC的解剖位置处于一个易损的功能性界面 ,其功能容易发生紊乱 ,并且与动脉粥样 Vascular endothelial cells (VECs) are monolayers of flattened cells lining the surface of blood vessels. Recent studies have shown that it not only plays a barrier role, but also has important endocrine function, involved in vascular injury repair and immune response, is known as the body’s largest endocrine and paracrine organs. Because of the VEC’s anatomical location at a delicate functional interface, its function is prone to disruption and is associated with atherosclerosis
