我们描述了协议的明源在体内的中性粒细胞趋化中性粒细胞招聘时测量动态的中性粒细胞 - 内皮细胞相互作用的活体显微镜。中性粒细胞腔内爬行,transendothelial迁移和趋化鼠标提睾肌组织与时间已过视频摄影和ImageJ跟踪观察。

该方案的总体目标是使用明场、活体显微镜和延时视频摄影来研究中性粒细胞募集过程中响应体内中性粒细胞化疗引诱剂的动态中性粒细胞内皮细胞相互作用。在本视频中,我们演示了如何使用明场活体视频显微来可视化和确定小鼠 chma 肌肉组织中中性粒细胞腔内爬行、T 内皮迁移和趋化性的程序。白细胞募集是炎症的标志。

当血液中的白细胞开始在炎症部位的毛细血管后静脉内皮上滚动时,这个募集过程就开始了。为了响应眼部表面的趋化因子或其他化疗引诱剂,这些滚动的白细胞停滞在内皮上并牢固地粘附在内皮上。粘附后,许多白细胞在管腔表面爬行,似乎在寻找最佳的迁移部位。
