血管通透性是微血管系统的主要功能,受血压、血液粘度和内皮屏障功能等多种因素调节。活体显微镜已用于直接评估体内血管通透性,从而可以在真正的生理血流动力学背景下准确测量内皮屏障功能。在这里,我们描述了测量脑海绵状血管瘤小鼠模型内皮屏障功能的程序,包括微量移液器准备、麻醉、气管切开术、颈静脉导管插入术、提睾解剖、成像和数据分析。这些动物表现出微血管通透性增加和血管形态异常,需要特别考虑。
Vascular permeability is a major function of the microvasculature that is regulated by multiple factors including blood pressure, blood viscosity, and endothelial barrier function. Intravital microscopy has been used to directly assess vascular permeability in vivo, which allows for the accurate measurement of endothelial barrier function in a truly physiological hemodynamic context. Here, we describe the procedure for measuring endothelial barrier function in mouse models of cerebral cavernous malformations, including micropipette preparation, anesthesia, tracheotomy, jugular catheterization, cremaster dissection, imaging, and data analysis. These animals exhibit an increase in microvessel permeability and abnormal vessel morphology, which require special consideration.
