在这里,我们描述了成年小鼠可行心室切片的制备及其对尖锐电极动作电位记录的应用。这些多细胞制剂提供了保留在体内的类似组织结构,这使得它们成为体外电生理和药理学研究的有价值的模型。

该技术的总体目标是获得适用于电生理记录的活心室心脏切片。这种方法可以帮助在组织水平上回答心脏电生理学领域的关键问题,例如移植心肌细胞的电整合或心脏活性药物的影响。该技术的主要优点是活的脑室组织切片具有保存的体内样组织结构,并且可以在心脏的所有区域进行直接测量。

虽然这种方法可以提供对小鼠心脏电生理学的见解,但它也可以应用于其他动物,如兔子或豚鼠。要开始此过程,首先用 70% 乙醇擦拭动物的皮肤。打开胸腔后,用小剪刀和镊子仔细解剖心脏的心包。
