技术原理

       表皮或内皮细胞之间通过紧密连接形成一层具选择性的细胞屏障，细胞屏障不仅控制邻近细胞间间隙对各种溶解物的扩散渗透率，而且调控跨细胞物质转运。细胞屏障的存在一方面保护了机体免受有害物质的伤害，另一方面也限制了ZL性药物的进入。

       细胞屏障的通透性可以通过跨膜电阻（即TEER，Transepithelial resistance)来反映，细胞屏障的通透性与跨膜电阻TEER之间的关系为：通透性越高TEER越低，反之亦然。

应用案例

■  用跨膜电阻（TEER）值法检测Caco-2细胞屏障的完整性

       用跨膜电阻（TEER）值法检测Caco-2细胞屏障的完整性。Caco-2细胞以5×10³细胞/孔的密度接种于Transwell小室中。周每隔一天更换一次新鲜培养基，然后在接下来的两周每天更换一次新鲜培养基。并使用NanoAnalytics公司 Cellzscope2软件对所得实时数据进行分析。

       Caco-2细胞培养19天后，细胞跨膜电阻值≥500 Ω·cm²，细胞形成一个完整的单层屏障，完整性通过Lucifer Yellow渗透性测试得到进一步得到证实，进而单层细胞屏障可用于下一步的运输实验。SRL和SRL NCs的细胞毒性呈浓度依赖性（图1B）。SRL和SRL-NCs的半数大YJ浓度分别为147.51μg/mL和165.41μg/mL。在50μg/mL的SRL和SRL-NCs作用72h后，细胞存活率保持在80%以上。这表明本研究中使用的SRL浓度不会引起显著的细胞毒性。因此，药物对细胞活力的影响可以忽略不计。

       转运实验采用完整紧密连接的肠上皮Caco-2细胞单层作为模型，SRL和SRL-NCs组的跨膜电阻（TEER）值（图1D）在整个转运过程中未显示出任何显著变化，表明在没有紧密连接遭到破坏的情况下，Caco-2细胞单层的完整性得以维持。

       将含药物HBSS缓冲液和空白HBSS缓冲液分别添加到模型顶层（AP）和基底外侧（BL）侧，模拟药物从GIT到血液的吸收和转运途径。也就是说，细胞层从GIT中运出药物并将其输送到血液/肠系膜淋巴。相反，当将药物HBSS缓冲液添加到BL侧和空白HBSS缓冲液添加到AP侧时，模拟了动物血液进入肠腔的过程。计算出SRL-NCs的流出速率由于Papp、BL-AP/Papp、AP-BL与SRL显著不同（图1C）。原因可能是药物被纳米化后药物变得更小，比表面积增加，因此跨单层的转运显著增强。另一种可能是细胞占据了整个SRL-NCs结构，因此与SRL组相比，通透性增强，SRL-NCs组AP→BL侧Papp高5.6倍，外排率低。

数据测试

1.细胞屏障的特性

 cellZscope可以连续监测细胞几天甚至几星期的生理状态。从cellZscope所提供的跨膜电阻值（TEER）和电容值（Ccl）这两个参数可以获知当前的细胞状态，包括融合度和分化度。CaCO2是源自人类结肠癌细胞系，通常用于药物转运研究，图中cellZscope跟踪记录了CaCO2细胞层的形成和分化的信息，自动化的记录了从接种细胞开始并持续观察21天。

长时间监测细胞屏障的形成

2.紧密连接动力学

上皮细胞和内皮细胞的跨膜阻抗值与细胞间紧密连接密切相关。紧密连接可影响细胞间物质转运过程。通过cellZscope测量细胞层跨膜电阻可以用于研究紧密连接动力学。图示MDCK细胞对不同浓度的EGTA的反应。
