发炎的内皮从流动招募白细胞的能力是由间充质基质细胞调节。我们描述两个体外结合原代人细胞,它可以用于从流动评估中性粒细胞募集和检查的作用是间充质基质细胞在调节这个过程中发挥的模型。
该程序的总体目标是检查组织驻留细胞如何影响血管内皮细胞在炎症期间支持白细胞募集的能力。这是通过首先使用两种体外血管模型之一(微载玻片模型和滤光片模型)建立内皮细胞与间充质干细胞的共培养物来实现的。然后在流式测定之前用细胞因子处理这些培养物。
然后,以逐步方式组装基于流的 aian 系统,并根据所使用的模型系统进行修改。最后一步是将白细胞灌注到内皮细胞上,并观察它们从流中募集以及随后的行为。最终,这些基于多细胞流式的粘附测定表明,间充质干细胞和内皮细胞之间的串扰抑制了炎症期间中性粒细胞的募集。
