[Abstract]  

The high attrition rate in drug development processes calls for additional human-based model systems. However, in the context of brain disorders, sampling live neuronal cells for compound testing is not applicable. The use of human induced pluripotent stem cells (iPSCs) has revolutionized the field of neuronal disease modeling and drug discovery. Thanks to the development of iPSC-based neuronal differentiation protocols, including tridimensional cerebral organoids, it is now possible to molecularly dissect human neuronal development and human brain disease pathogenesis in a dish. These approaches may allow dissecting patient-specific treatment efficacy in a disease-relevant cellular context. For drug discovery approaches, however, a highly reproducible and cost-effective cell model is

[摘要]  [摘要]药物开发过程中的高流失率要求使用其他基于人的模型系统。但是,在脑部疾病的情况下,不适合对活的神经元细胞进行采样以进行化合物测试。人类诱导的多能干细胞(iPSC )的使用彻底改变了神经元疾病建模和药物发现领域。由于基于iPSC的神经元分化方案(包括三维脑类器官)的发展,现在可以在一个碟子中分子解剖人神经元发育和人脑疾病的发病机理。这些方法可以允许在与疾病相关的细胞环境中解剖患者特异性的治疗功效。但是,对于药物发现方法,需要高度可复制且具有成本效益的细胞模型。在这里,我们描述了一种一步-步骤,用于从人产生健壮和可膨胀的神经祖细胞(NPC)工艺的iPSC 。用此协议生成的NPC是同质的且高度增殖。这些功能使NPC适合开发用于药物发现的高通量化合物筛选。人iPSC衍生的NPC示出了代谢依赖于线粒体活性,因此可也用于研究神经病症,其中线粒体功能受到影响。该协议涵盖了制备,培养和表征人iPSC来源的NPC所需的所有步骤。

[Abstract]  Induced pluripotent stem cells (iPSCs) are genetically reprogrammed somatic cells that exhibit features identical to those of embryonic stem cells (ESCs). Multiple approaches are available to derive iPSCs, among which the Sendai virus is the most effective at reprogramming different cell types. Here we describe a rapid, efficient, safe, and reliable approach to reprogram human fibroblasts into iPSCs that are compatible with future iPSCs uses such as genome editing and differentiation to a transplantable cell type. [摘要]  [摘要] 诱导多能干细胞(iPSCs)是一种经过基因重组的体细胞,具有与胚胎干细胞(ESCs)相同的特性。有多种方法可以获得iPSCs,其中仙台病毒是最有效的重编程不同的细胞类型。在这里,我们描述了一种快速、高效、安全、可靠的方法,将人类成纤维细胞重新编程为与将来iPSCs相兼容的iPSCs,如基因组编辑和分化为可移植细胞类型。

[背景] 诱导多能干细胞(iPSCs)是经过基因重组的成体细胞,其形态和功能特性与胚胎干细胞(esc)非常相似(Takahashi和Yamanaka,2006;Yu等人,2007)。它们不仅为疾病建模提供了一个很好的机会,而且为涉及组织退化的病理学的治疗策略的发展提供了一个很好的机会。此外,iPSCs的承诺依赖于一个安全的可补充的细胞源,来源于化学定义的培养基中,并且没有随机的DNA整合。
将体细胞重编程为iPSCs需要强制表达支持多潜能状态的转录因子,包括OCT4、SOX2、KLF4、c-MYC、NANOG和LIN-28(Takahashi和Yamanaka,2006;Takahashi等人,2007;Yu等人,2007)。有多种方法可以将转录因子传递到细胞中,包括那些需要整合到宿主染色体中的方法(Takahashi and ...
