这项研究得到了国家多发性硬化协会 (RG4591A1/2) 和国立卫生研究院 (R03NS06740402) 的赠款的支持。作者感谢 Ivan 博士及其实验室成员提供实验室空间、设备和建议。

本研究中使用的小鼠根据纽约州立大学南部医学中心实验室动物资源 (DLAR) 协议15-10492 号的指导方针予以照顾。

本文提出了一种高效分离高纯度未成熟小鼠少突胶质培养的方法。与以前发布的协议39、40相比, 此方法产生了更高的纯度, 具有低得多的 GFAP 阳性星形胶质细胞和其他非特征细胞的极低百分比。重要的是要指出, 这些是未成熟的生命线行动已经致力于 oligodendroglial 血统。因此, 这些细胞对于研究分化的早期阶段是不有用的。

少突胶质 (生命线) 是中枢神经系统 (CNS)1 的 myelinating 细胞。在严格调节的环境中, 主少突胶质的分离和培养是体外研究 oligodendroglia 的重要工具, 也是脱髓鞘疾病 (如多发性硬化症) 的生物学基础2.这需要一个高效且健壮的少突胶质隔离和区域性方法3。在本研究中, 我们利用了一个独特的少突胶质细胞表面标记的表达, 以实现一个快速和具体的改进的隔离技术。
已经确定了四个不同的少突胶质成熟阶段, 每一个发育阶段都表现出独特的细胞表面标记(图 1)。这些单元格表面标记可以通过特定的抗体4、5识别, 并可用于在特定阶段隔离生命线。在第一阶段, 少突胶质前体细胞 (OPCs) 有能力增殖, 迁移, 并明确表达血小板衍生生长因子受体 (血小板 Rα)6, 苷 A2B5, 蛋白多糖NG27, 8, 聚唾液酸-神经细胞黏附分子9和脂肪酸结合蛋白 7 (FABP7) 10. OPCs 具有双极性形态学, 细胞体的对立两极产生的短过程很少, 这是神经前体细胞11的特征。
<img alt="Figure 1" class="xfigimg" src="/files/ftp_upload/57543/57543fig1v2.jpg"> 图 1: 在鼠标少突胶质开发过程中单元格表面标记的表达式。A2B5、GalC (O1)、NG2、O4 和血小板因子 Rα等生命线细胞表面标记物可用于在特定发育阶段用特定抗体分离少突胶质。  <a href="//cloudflare.jove.com/files/ftp_upload/57543/57543fig1v2large.jpg" target="_blank">请单击此处查看此图的更大版本.</a>
在第二阶段, OPCs 产生 preoligodendrocytes 和表达的细胞膜不仅 OPC 标记, 而且 sulfatide (硫酸 galactolipid) 承认 O4 抗体12,13, GPR17 蛋白14,一直持续到未成熟的少突胶质 (OL) 阶段。在这个阶段, preoligodendrocytes 扩展多极短过程。Preoligodendrocytes 是大鼠和鼠脑白质中 2 (P2) 的主要 OL 阶段, 其小种群为未成熟的生命线15。
在第三阶段, 未成熟的生命线继续表达 O4, 失去 A2B5 和 NG2 标记的表达, 并开始表达 galactocerebroside C16。在这个阶段, 苏丹生命线行动致力于 oligodendroglial 谱系, 成为后有丝分裂细胞与长分支分支17,18。未成熟的 OL 构成80% 以上的啮齿动物白色物质在 P7 和此时第一个 MBP+单元格被观察15,19,20,21。因此, 在 P7 中分离生命线能保证细胞高产。
在 OL 发育的最后和第四阶段, 成熟的 myelinating 蛋白 (髓鞘碱性蛋白 (MBP), proteolipid 蛋白 (), 髓鞘相关糖蛋白 (MAG) 和髓鞘少突胶质糖蛋白 (MOG) 22, 23 ,24,25,26。在这个阶段, 成熟的生命线延伸膜, 形成紧凑的包裹鞘围绕轴突和能够 myelinate。这与观察老鼠和老鼠大脑的情况一致, 在 P1419,20,21中, MBP+细胞变得越来越丰富。
自从 Fewster 和同事在1967年首次隔离少突胶质27 以来, 已实施了几种方法, 用于从啮齿动物中枢神经系统中分离生命线, 其中包括immunopanning28、29、30、荧光活化细胞分选 (资产管制署) 利用细胞表面特异抗原28,31, 差分梯度离心32,33,34,35和基于不同中枢神经胶质细胞差异粘附的震动方法36,37。然而, 现有的文化方法有局限性, 特别是在纯度、产量和执行程序38所需的时间方面。因此, 需要更有效的少突胶质隔离方法。
本文提出了一种简便、有效的选择方法, 用于磁三 O4+ preoligodendrocytes 细胞与新生小鼠幼崽的分离。此方法是对金刚砂et所报告的技术的修改。39和 Dincman et 。40 , 并提供在大约4小时以上80% 的少突胶质制备纯度。

rapid and specific immunomagnetic isolation of mouse primary oligodendrocytes

高效、健壮的分离和培养原少突胶质 (生命线)是体外研究 oligodendroglia 的重要工具, 也是脱髓鞘疾病 (如多发性硬化) 的生物学和Pelizaeus Merzbacher 样疾病 (PMLD)。在这里, 我们提出了一个简单而有效的选择方法, 磁隔离三期 O4+ preoligodendrocytes 细胞从新生小鼠幼崽。由于未成熟的 OL 在产后 7 (P7) 的啮齿动物脑白质中占80% 以上, 这种隔离方法不仅保证了高细胞的产量, 而且还对已经致力于 oligodendroglial 谱系的生命线的具体隔离, 减少了可能隔离污染的细胞, 如星形胶质细胞和其他电池从老鼠的大脑。这种方法是对以前报告的技术的修改, 并提供少突胶质的纯度在80% 以上约4小时。

本研究的目的是为 O4+主鼠标少突胶质建立一个改进的隔离方法, 要求对目标单元格进行尽可能少的操作。整个过程从幼崽的安乐死到电镀细胞在盖玻片需要大约 4 h, 并且这里显示的数据代表三个独立实验。组织离解后, 每项独立实验的平均 4.3 0.46 x 107细胞被隔离, 其生存能力为 91% @ 5.6%。在使用 anti-O4 标记磁性微珠磁隔离之后, 平均获得了6.9 个 0.38 x 106</...
