人臍靜脈內皮細胞說明：
貨號：8000


血管內皮細胞對維持血管動態平衡起著重要作用。它們合成、分泌凝血和纖溶系統的激活因子和抑制因子、影響血
小板粘附和聚集的調節因子。內皮細胞還釋放控制細胞增殖和調節血管壁緊張度的分子。這些過程都可以用培養的
細胞進行體外研究，人臍靜脈和動脈內皮細胞是這類研究中最常用的細胞類型。除了普通的內皮細胞特征例如
“鵝卵石狀”，VIII因子陽性著色，能攝取乙酰基化低密度脂蛋白，人臍血管內皮細CD31染色陽性。用IL-1或TNF-α
預先處理過的細胞也能選擇性地表達E-selectin和VCAM。 人臍靜脈內皮細胞(HUVEC)提取于人臍帶靜脈組織，
原代凍存。每管含有細胞數>5×105 cells/ml，此細胞通過vWF/Factor VIII 和CD31 (P-CAM)免疫熒光染色驗證，
經測試不含有HIV-1、HBV、HCV、支原體、細菌、酵母和真菌。細胞可以達到15倍增。

推薦培養基:(ECM, Cat. No. 1001)

The vascular endothelial cells contribute to the maintenance of vascular homeostasis. They 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. Many of the endothelial processes
can be studied in vitro using cultured cells, and human umbilical vein endothelial cells (HUVEC) are the
most commonly used cell type for such studies. Except for the common endothelial cell features such as
"cobblestone" morphology, positive staining for Factors VIII and the ability to take up acetylated low-density
lipoprotein [1], HUVEC stein positively with CD-31 [2]. Cells pretreated with IL-1 or TNF-alpha also selectively
express E-selectin [3] and VCAM [4].
HUVEC from ScienCell Research Laboratories are isolated from human umbilical vein. HUVEC are
cryopreserved at passage one and delivered frozen. Each vial contains >5 x 105 cells in 1 ml volume. HUVEC
are characterized by immunofluorescent method with antibodies to vWF/Factor VIII and CD31 (P-CAM)
and by uptake of DiI-Ac-LDL. HUVEC are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and
fungi. HUVEC are guaranteed to further expand for 15 population doublings at the conditions provided by
ScienCell Research Laboratories.
