我们在这里提出了一种优化的方案,用于对胎鼠进行基因分型、染色和准备,用于对整个动物的外周伤害感受器轴突投射进行成像,作为评估发育中基因工程小鼠的感觉轴突生长表型的有效方法。
以下实验的总体目标是有效评估发育中的胎鼠的感觉轴突生长表型。这是通过首先对 tre a tau 松弛报告小鼠进行正确育种和基因分型来实现的,以便可以作为第二步进行下游染色测定。小鼠胚胎被固定和染色,以允许在整个动物中可视化感觉轴突投射。
接下来,胚胎脱水并清除,以完全可视化原本不可见的深层轴突突起。结果表明,这些方法是快速评估胚胎伤害感受轴突生长表型的有效手段。使用 track a Tau Lae 报告基因,该方法可以帮助回答感觉轴突生长领域的关键问题,方法是允许研究人员将他们感兴趣的基因交叉到 track a tlac Z 背景上并筛选感觉轴突生长表型的任何变化。
