[Abstract]  Vascular leakage is an important feature in several diseases, such as septic shock, viral hemorrhagic fever, cancer metastasis and ischemia-reperfusion injuries. Thus establishing assays for measuring endothelial permeability will provide insight into the establishment or progression of such diseases. Here, we provide transwell permeability assay and electrical impedance sensing assay for studying endothelial permeability in vitro. With these methods, the effect of a molecule on endothelial permeability could be defined. [摘要]  血管渗漏是脓毒性休克,病毒性出血热,癌症转移和缺血再灌注损伤等几种疾病的重要特征。因此,建立测定内皮通透性的测定将提供对这些疾病的建立或进展的洞察。在这里,我们提供transwell渗透性测定和用于研究体内内皮通透性的电阻抗感测测定。通过这些方法,可以定义分子对内皮通透性的影响。

背景 内皮屏障是一个良好调节的结构,其在正常生理条件下保持对流体和分子的最小和选择性渗透性(Komarova和Malik,2010)。内皮屏障的破坏在暴露于炎性细胞因子,病原体感染或癌症转移中发生,其诱导细胞骨架,细胞 - 细胞连接或细胞与基质附着的破坏。血管通透性的增加是许多疾病的重要特征,包括缺血再灌注损伤,败血症,病毒性出血热和癌症。为了筛选哪个分子调节血管通透性,有必要建立体外的体外试验以在扩张到动物研究之前测试内皮通透性。有两种可用的体外试验体外渗透性试验,transwell渗透性测定法和电阻抗检测装置(Bischoff等,2016)。 ...
