[Abstract]  Angiogenesis, the growth of new blood vessels from pre-existing vessels, is a critical process that occurs during normal development and tumor formation. Targeting tumor angiogenesis by blocking the activity of vascular endothelial growth factor (VEGF) has demonstrated some clinical benefit; nevertheless there is a great need to target additional angiogenic pathways. We have found that the human umbilical vein endothelial cell (HUVEC) fibrin bead sprouting assay (FBA) is a robust and predictive in vitro assay to evaluate the activity of angiogenesis inhibitors. Here, we describe an ... [摘要]  血管发生,来自预先存在的血管的新血管的生长是在正常发育和肿瘤形成期间发生的关键过程。通过阻断血管内皮生长因子(VEGF)的活性靶向肿瘤血管生成已经证明了一些临床益处;然而,非常需要靶向额外的血管生成途径。我们已经发现,人脐静脉内皮细胞(HUVEC)纤维蛋白珠发芽测定(FBA)是评估血管生成抑制剂的活性的稳健的和预测性的体外测定。在这里,我们描述了用于评估血管生成的生物抑制剂和关键终点的自动定量的优化的FBA方案。

[背景] 血管发生,新血管的生长从先前存在的血管,是在伤口愈合和正常发育期间发生的生理过程。血管生成是一个复杂和高度调节的过程,涉及内皮细胞增殖,分化,迁移,基质粘附和细胞间的信号的紧密协调。血管发生也严重参与肿瘤发展和转移。事实上,通过阻断血管内皮生长因子(VEGF)的活性靶向肿瘤血管生成已经证明了临床益处。由于肿瘤最终对VEGF靶向治疗产生抗性,因此非常需要靶向额外的血管生成途径。我们已经发现人脐静脉内皮细胞(HUVEC)纤维蛋白珠发芽测定(FBA)(Nakatsu等人,2007; Nakatsu和Hughes,2008; ...
