人主动脉内皮细胞
上海义森生物科技有限公司
内皮细胞构成了血管和其下组织的交界面。内皮细胞功能的变化是动脉粥样硬化的发病机理中的关键因素。内皮细胞能合成分泌凝血系统和纤溶系统中的活化因子和YZ因子，同时也能合成和分泌影响着血小板粘附和聚集的某些介质。内皮细胞还可以释放具有调控细胞增殖和血管壁张力功能的分子。人主动脉内皮细胞能生成诸如t-PA 和 PAI-1等抗凝和血栓形成因子；在TNF-alpha的调节下，人主动脉内皮细胞能改变其生长特性，产生GM-CSF等细胞因子，在细胞表面表达ICAM-1，并产生大量的NO和内皮素。许多内皮水平的过程多可以通过内皮细胞的体外培养进行研究，因此，HAEC非常适用于研究和认识血管病变和衰老的分子机理。 人主动脉内皮细胞(HAEC)提取于人主动脉组织，原代冻存。每管含有细胞数>5×105 cells/ml，此细胞通过vWF/Factor VIII 和CD31 (P-CAM)免疫荧光染色验证，经测试不含有HIV-1、HBV、HCV、支原体、细菌、酵母和真菌。细胞可以达到15倍增。

Endothelial cells constitute the natural interface between the blood and the underlying tissue. Changes in endothelial cell function appear to play a key role in the pathogenesis of atherosclerosis. Endothelial cells synthesize and secrete activators as well as inhibitors of both the coagulation system and the fibrinolysis system in addition to mediators that influence the adhesion and aggregation of blood platelets. Endothelial cells also release molecules that control cell proliferation and modulate vessel wall tone [1]. Human aortic endothelial cells (HAEC) produce antithrombotic and thrombotic factors such as t-PA and PAI-1 and respond to TNF-alpha by modifying growth characteristics, producing cytokines such as GM-CSF, expressing ICAM-1 on the surface and producing large amounts of nitric oxide and endothelin [2]. Many of the endothelial processes can be studied in vitro using cultured cells, and HAEC will surely be very useful to studying and understanding the molecular mechanisms involved in many vascular alteration pathologies as well as in the aging process.
HAEC from ScienCell Research Laboratories are isolated from human aorta. HAEC are cryopreserved at passage one and delivered frozen. Each vial contains >5 x 105 cells in 1 ml volume. HAEC are characterized by immunofluorescent method with antibodies to vWF/Factor VIII and CD31 (P-CAM) and by uptake of DiI-Ac-LDL. HAEC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HAEC are guaranteed to further expand for 15 population doublings at the conditions provided by ScienCell Research Laboratories.
