本文的目的是描述了miRNA的原位杂交协议，在福尔马林固定的肾组织效果很好。虽然制定这个协议染色神器的几个重要来源已经确定。仔细注意这几点可以帮助避免染色神器，增加成功的ISH执行的可能性。 可以发生一个染色神器的最可避免的原因时，组织切片成为在漫长的孵化干涸。当此发生时变成干燥的组织部分将NBT / BCIP发育（ 图1）中染色很暗。在本?...

微RNA是小（约22个核苷酸长），非编码所产生的内源性的RNA。他们一般通过功能翻译抑制或mRNA降解，抑制蛋白的表达。的miRNA结合到靶mRNA不完全互补，从而有可能为一个单一的miRNA抑制多个目标。 了解哪些类型的细胞和结构表达的miRNA是理解机制的重要组成部分，通过它在miRNA的表达影响细胞和组织表型的改变。而方法如miRNA的测序，定量PCR和Northern杂交可用于检测在整个组织中的miRNA，这种方法不允许之一，以确定哪个特定的细胞类型，他们从一个给定组织中来了。使用这些方法和蜂窝结构成分分析之前夹层可以是非常困难的，以获得足够的隔离度所需的条件能导致人terations在基因表达或RNA的降解。微小RNA 原位杂交是用于可视化组织中微小RNA的位置和表达水平的方法。这种技术是在组织异质结构，如肾组成的特别有价值。 小分子RNA已被证明发挥肾脏发育2,3和生理学4的调节作用。微小RNA表达的改变也被证明参与与肾脏病理如纤维化5-10，糖尿病肾病7，肾癌11,12，和急性肾损伤13。在我们的研究中，我们已经发现， 在对肾组织原位杂交优化微小RNA是用于确定miRNA的表达在健康和疾病14的确切结构的位置有价值。不同的microRNA的管状和细胞表达的测定是很重要的，因为TA自己调节rgets可能依赖于细胞功能。在疾病状态也很重要，以确定如何在miRNA表达的改变可能影响功能。 这里描述的方法的目标是建立在由Kloosterman 等 15，其他研究者16,17开发现有ISH方法，以及那些建议的Exiqon 1和优化方法对福尔马林固定的肾组织。我们已经成功地使用这种方法来确定单侧输尿管梗阻18在肾小分子RNA的miR-382的表达明显的地区差异。这种方法可以与其他组织可以用作良好，额外的优化。
