摘要 组织因子(TF)在肿瘤转移方面已被广泛研究,但其在介导癌细胞粘附到脉管系统中的作用仍不清楚。本研究旨在测定 TF 介导乳腺癌细胞与人脐静脉内皮细胞 (HUVEC) 粘附的能力。 MDA-MB-231 细胞表达最高的 TF 水平,并且在静态和流动条件下对 HUVEC 的粘附程度更高,中和 TF 抗体消除了 MDA-MB-231 细胞对 HUVEC 的增强粘附。重组人可溶性TF(rTF)将β1整合素结合在HUVEC表面,β1或α3整合素抗体与TF抗体结合可消除更多的细胞间粘附。这些数据表明TF介导的乳腺癌细胞与内皮细胞的粘附可能依赖于HUVEC表面的β1整合素。
ABSTRACT Tissue factor (TF) has been extensively studied for tumor metastasis, but its role in mediating cancer cell adhesion to vasculature remains unknown. This study aimed to measure the ability of TF to mediate the adhesion of breast cancer cells to human umbilical vein endothelial cells (HUVECs). MDA-MB-231 cells expressed the highest TF level and adhered more to HUVECs under static and flow conditions, a neutralizing TF antibody abolished the enhanced adhesion of MDA-MB-231 cells to HUVECs. Recombinant human soluble TF (rTF) bonded β1integrin on HUVECs surfaces, β1 or α3integrin antibody combined with TF antibody abolished more cell-cell adhesion. These data suggested that TF mediated adhesion of breast cancer cells to endothelial cells may rely on β1integrin on HUVECs surfaces.
