Summary

这是一个描述如何分离并培养颈上神经节(SCG)的新生幼鼠的主要交感神经元的协议。

Abstract

颈上神经节(SCG)在大鼠小,有光泽,杏仁状结构,其中包含交感神经元。这些神经元提供的头部和颈部区域的交感神经支配,它们构成了一个良好的特点和人口相对同质化(4)。交感神经元是依赖于神经生长因子(NGF)的存活,分化和轴突生长和广泛的传播,神经生长因子的空房情况,有利于他们的文化和实验操作(2,3,6)。基于这些原因,培养的交感神经元,已被用于各种各样的研究,包括神经元的发育和分化,编程和病理细胞死亡的机制和信号转导(1,2,5,6)。解剖SCG从新生大鼠和培养交感神经元是不是很复杂,可以掌握相当迅速。在这篇文章中,我们将详细描述了如何剖析,从新生幼鼠在SCG并使用它们来建立培养的交感神经元。文章还将介绍预备步骤和各种试剂和实现这一目标所需要的设备。

Protocol

1。解剖的筹备工作: 选择适当的培养皿(10厘米或6孔板或24孔板等)取决于您的实验性质,和大衣与鼠尾胶原24小时前清扫。准备鼠尾胶原蛋白,并用它来大衣培养皿的方法已在别处(1)。 准备0.25%胰蛋白酶溶液中的磷酸缓冲液(PBS)(无EDTA)和过滤消毒。准备1毫升分装和存储-20℃ 准备一个解决方案包含在蒸馏水/去离子H 2 O 2.5毫米尿苷和5 – FDU过滤消毒,并准备50…

Discussion

我们用我们的文化SD大鼠。

需要时间和护理,清洗时的神经节。取出所有碎片,血管和脂肪。在确保文化,是多还是少均匀,无多余的细胞类型,这一步很重要。 uridine/5-FDU此外,将在很大程度上消除污染的文化任何剩余的非神经细胞(有丝分裂),或至少抑制其增殖。

此外,在解离步骤,耐心,花时间来单独的神经元,使他们没有发现在大的团块,一旦被接种到板块。大团块细胞不会产生良好的实?…
