离体灌注肾脏鼠标是用于在受控环境中的体外研究肾功能1小时，架桥在完整的动物体内实验，这可以通过许多全身性因素的影响，是有缺陷的之间的间隙的一个工具，并在体外实验中分离的肾段或培养细胞，这必然忽视完整器官结构对功能的影响。还有就是，以作者的知识，没有替代技术，用以执行这一特定的任务。对肾组织的生化研究，然而，可以在使用肾脏切片17</sup...

器官的隔离灌注一直生理学家中不断努力的主题几十年1。该技术使器官的功能，而没有全身的影响，如血压，激素，或神经，进行研究。卡尔·爱德华Loebell被认为是第一个所描述的一个孤立肾灌注成功，于1849年2。此后，灌注设备发生了显著细化。弗雷和格鲁伯引入了氧合搏动泵人工肺的连续灌流2。虽然早期的研究人员重点研究大型哺乳动物-即，猪2和狗3使用大鼠肾脏的-the第一份报告，魏斯等人的肾脏。 ，是小型哺乳动物器官灌注4研究的一个里程碑。 Schurek 等。报道添加哺乳动物红细胞到灌流如果有足够的肾小管的必要性氧合要达到5。临界长期实验是由相同的研究组6引进缓冲器的连续透析。在2003年，Schweda 等。是第一个报告功能的鼠标离体灌注肾（MIPK）7，后来被Rahgozar 等精制而成。 18和林德尔等。 14。 虽然在技术上不是孤立肾灌注大鼠更具挑战性，使用MIPK负有能够使用各种各样基因改造的小鼠中的优势。本文介绍了作者的方法的详细信息隔离灌注小鼠肾1小时。该方法允许对肾流量，血管阻力，激素释放，血气分析，尿液分析，以及药物的应用程序的连续评估。以下的方法，肾脏可以用于分子和生化分析进行处理，是固定的显微镜，或移植到受体小鼠（ 图1）。 <img alt="图1" src="/files/ftp_upload/54712/54712fig1.jpg" /> 图1：可能的输入/输出到离体肾的概述。 BGA：血气分析。 <a href="http://ecsource.jove.com/files/ftp_upload/54712/54712fig1large.jpg" target="_blank">请点击此处查看该图的放大版本。</a> 这种技术可能会得到更多的关注，未来数年，多创新应用正在与长期常温肾脏血流灌注的曙光移植前的讨论（含或不含抗排斥或基因组编辑药物的应用）8，9，10 11，从脱细胞支架12整个肾脏的生物工程，剂量和高剂量荧光染料对多光子成像13应用</sup&gt;。这也是与研究急性肾损伤14中特定基因的作用的理想模型。 一个一步一步的协议，是考虑到让其他实验室成功地执行孤立的小鼠肾脏灌注。首先，组合物和制剂的缓冲液中被指定。然后，手术中详细描述和示出的关键步骤。第三，数据呈现的是，用于展示成功制备的：肾血流量，血管阻力，肾小球滤过率和分数电解质排泄-所有灌注肾脏的不同肾段的形态的生存能力和透射电子显微照片的功能性测量灌注后的1小时固定。
