isolation, enrichment, and maintenance of medulloblastoma stem cells

脑肿瘤已建议拥有人口少的干细胞，是肿瘤发生的根本原因。神经球分析已普遍采用，以研究神经干细胞，包括那些来自正常和肿瘤组织的性质。然而，分化和细胞死亡的可观的金额，共同培养的神经球，很可能是由于次优的条件，如细胞培养液中在所有领域聚集内无障碍。 髓母细胞瘤，小儿中枢神经系统最常见的肿瘤，其特点是它的快速进展和扩散趋势沿整个脑脊髓轴与惨淡的临床结果。髓母细胞瘤是小脑的神经上皮肿瘤，约占颅内和后颅窝肿瘤的童年的20％和40％， 分别为1。现在是完善的，Shh信号刺激小脑颗粒神经元前体（CGNPs）的增殖， 在小脑发展2-4。许多研究使用的小鼠模型，在SHH通路组成激活，与髓母细胞瘤5-9 Shh信号。 最近的一份报告表明，从Patched1 LacZ基因/ +小鼠的髓母细胞瘤细 ​​胞的一个子集，是癌症的干细胞，这是能够启动和propogating肿瘤10。在这里，我们描述组成激活SHH通路由于在理顺突变（11，关于此简称为SmoM2），一个GPCR的关键是嘘隔离开来，丰富和维护几个髓母细胞瘤小鼠模型的肿瘤干细胞的有效方法，通路的激活。在每一个孤立的髓母细胞瘤组织，我们能够建立大量高度增生的殖民地。强劲表达一些神经干细胞标记物，如巢和Sox2这些细胞，可以进行串行通道（大于20），克隆形成。虽然这些培养的​​肿瘤干细胞相对较少，往往与高核质比，有利于干细胞生长的条件下培养时bipoar，他们极大地改变它们的形态，扩展多种细胞过程，夷为平地，从细胞周期退出后，切换到一个单元格辅以10％胎牛血清的培养基。更重要的是，这些肿瘤干细胞分化成Tuj1 +或NeuN +神经元，GFAP +的星形胶质细胞和CNPase +少突胶质细胞，从而突出其多效力。此外，这些细胞能够传播继发髓母细胞瘤原位移植到宿主小鼠​​时。
