肾小球滤过率 (GFR) 的透皮分析是一种成熟的技术,用于评估急性肾损伤和慢性肾病小鼠和大鼠模型的肾功能。该测量系统由一个微型荧光检测器组成,该检测器直接附着在有意识、自由活动的动物背部的皮肤上,并测量外源性 GFR 示踪剂、荧光素-异硫氰酸酯 (FITC) 结合的左氨菊素(一种菊粉类似物)的排泄动力学。该系统已在大鼠身上进行了详细描述。然而,由于其尺寸较小,对小鼠经皮 GFR 的测量提出了额外的技术挑战。因此,在本文中,我们根据多年来在小鼠中进行这种测定的三位不同研究人员的综合经验,提供了在小鼠中使用透皮 GFR 监测仪的第一份详细的实用指南。
Transdermal analysis of glomerular filtration rate (GFR) is an established technique that is used to assess renal function in mouse and rat models of acute kidney injury and chronic kidney disease. The measurement system consists of a miniaturized fluorescence detector that is directly attached to the skin on the back of conscious, freely moving animals, and measures the excretion kinetics of the exogenous GFR tracer, fluorescein-isothiocyanate (FITC) conjugated sinistrin (an inulin analog). This system has been described in detail in rats. However, because of their smaller size, measurement of transcutaneous GFR in mice presents additional technical challenges. In this paper we therefore provide the first detailed practical guide to the use of transdermal GFR monitors in mice based on the combined experience of three different investigators who have been performing this assay in mice over a number of years.
