从鼠耳和尾组织生成主成纤维细胞培养
Summary
我们描述用于产生从耳朵和小鼠的尾部的成纤维细胞初级一个简单而快速的实验程序。该过程不需要特殊的动物训练和可用于成纤维细胞培养的产生从存储在RT至10天耳朵。
Abstract
原代细胞是直接从组织来源和被认为是更具有代表性的细胞在体内比建立的细胞系的生理状态。然而，原代细胞培养，通常具有有限的寿命，需要频繁重新建立。成纤维细胞是原代细胞的一个方便的来源。在这里，我们讨论一个简单而快速的实验程序，以建立从耳朵和老鼠尾巴初级成纤维细胞培养。该协议可以用于建立初级成纤维细胞培养从存储在RT至10天耳朵。当协议是经过精心接着，污染物是不太可能发生尽管使用储存延长的时间在某些情况下，非无菌的组织。成纤维细胞增殖迅速在培养和接受复制衰老之前可扩展到相当数量。
Introduction
主细胞来源于体外条件下活组织进行培养。它通常假设原代细胞更接近生理状态和其原始比永生化或肿瘤细胞系1的组织的遗传背景。出于这个原因，原代细胞代表用于研究生物学问题2,3的有用模型。然而，不同于无限增长建立的细胞系，原代细胞最终经历衰老中培养并需要经常重新建立。
常用的原代细胞包括成纤维细胞，上皮细胞，内皮细胞，T细胞，B细胞，骨髓衍生的巨噬细胞（BMDM）和骨髓来源的树突细胞（BMDC）。成纤维细胞通常用作原代细胞培养模型。它们提供超过其他初级细胞关键优势。细胞培养物容易建立，容易地维持和不需要purifica用前，培养细胞。他们有快速的初始扩散和专门的媒体或活化协议没有要求。成纤维细胞可以使用的生物，化学和物理协议4,5-有效地转染。有一种可能性，以存储耳朵之前建立的细胞培养物达10天室温。成纤维细胞培养有利于胞质突起的可视化和适于重新编程成诱导多能干细胞（iPS）6。
成纤维细胞是结缔组织的重要细胞分泌胶原蛋白和细胞外基质7。它们所提供的结构框架在许多组织8和播放在伤口愈合和组织修复9,10-必不可少的作用。
在这里，我们描述了一个简单而快速（<4小时）协议来建立从耳朵成纤维细胞培养和小鼠11尾。该协议需要最少的鼠标经验收获组织（相对于其它协议12,13），并且可以用于建立从存储在介质在RT至10天耳朵培养物。

Discussion
在这里，我们提供了一种简单，廉价且快速的实验步骤建立从耳朵和小鼠的尾巴初级成纤维细胞培养物。提取应导致粘附和迅速分裂成纤维细胞内后3天的隔离组织。原代细胞的一个重要的限制是衰老，一个永久生长停滞15。使用的协议，成纤维细胞培养可传代5-6次之前的成纤维细胞变得衰老，通过细胞的扁平化表示，尺寸增加（2-3倍增加）和故障扩大。
