Retraction Notice
The article Assisted Selection of Biomarkers by Linear Discriminant Analysis Effect Size (LEfSe) in Microbiome Data (10.3791/61715) has been retracted by the journal upon the authors' request due to a conflict regarding the data and methodology. View Retraction Notice
来源:Strüder, D., et al. 无毛小鼠耳垂中的活体显微镜检查和血栓诱导。 (2017 年)
该视频演示了活体荧光显微镜技术在小鼠模型中研究血栓形成。向小鼠注射荧光团标记的多糖以监测血液循环。在用高强度光照射时,耳微血管系统损伤的光毒性诱导导致血栓的形成,这可以通过可视化血流阻塞来证实。
所有涉及动物模型的程序均已由当地机构动物护理委员会和 JoVE 兽医审查委员会审查。
1. 动物的预先安排
2. 左颈静脉的制备和 FITC-葡聚糖的注射
注意:对于右耳的显微镜检查,请准备左颈静脉。
3. 活体荧光显微镜检查的右耳定位
4. 活体荧光显微镜检查和右耳血栓诱导

图 1.颈静脉的准备 (A) 和用于活体显微镜检查的耳朵的放置 (B)。(A) 使用手术立体显微镜,准备右颈静脉。在注射 FITC-葡聚糖之前缝合用于放置左耳的缝合线。左颈静脉先前解剖的伤口用经皮缝合线 (B) 闭合。左耳用聚丙烯 7/0 缝合线固定。小心放置盖玻片,不要压迫耳朵的基底血管。加热板在整个实验过程中保持动物的体温。
