内皮细胞是血管内膜表面一层单层扁平或多角形细胞。内皮不仅是血液和间质组织之间的一道生理屏障,还通过代谢、生成、激活和释放多种血管活性物质,发挥重要的功能。这包括调节血管收缩、抑制血小板活性,维持凝血和纤溶之间的平衡,调节炎症细胞的附壁。完整的内皮对维持血管内环境的稳定和调节血管收缩、血管形成抗炎、抗凝血具有重要意义。已有许 Endothelial cells are monolayer flat or polygonal cells on the surface of vascular intima. The endothelium is not only a physiological barrier between blood and interstitial tissue, it also plays an important role by metabolizing, generating, activating and releasing multiple vasoactive substances. This includes regulating vasoconstriction, inhibiting platelet activity, maintaining the balance between coagulation and fibrinolysis, and regulating the attachment of inflammatory cells. Endothelial integrity to maintain the stability of the vascular environment and regulate vasoconstriction, vascular anti-inflammatory, anti-coagulation is of great significance. Already
