在这里,我们描述了在成熟的主动脉收缩模型中手术主动脉脱体的分步协议。这个过程不仅允许研究左心室反向改造和肥大回归背后的机制,而且还可以测试可能加速心肌恢复的新疗法方案。
主动脉去除是研究啮齿动物心肌反向改造的有用实验模型,也是对心肌细胞回归和等离子体功能恢复机制的令人陶醉的新见解。这些金属有助于 VIVO 中批判反向建模的演变,以及在疾病进展期间不同时间点收集生物样本,用于体外和分子研究。该技术模拟心肌改造和反向改造的进展,并允许探索心肌恢复不完整的机制。
该协议提供了对长期压力超载相关病理(如眼部自命不忠或主动脉狭窄)中完全和不完整的心肌反向改造的机制和线的见解。将骨质疏松管连接到呼吸机,启动机械通风,并将呼吸机调整为每分钟 160 次呼吸的频率和每公斤 10 毫升的潮汐体积。在开始带状手术之前,确认六到八周大的C57黑六只小鼠对疼痛反射缺乏反应,刮胡子,将脱毛霜从颈线涂到小鼠的中胸水平,并将软膏涂在动物的眼睛上。
