[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]  Primary culture of mouse hippocampal neurons is a very useful in vitro model for studying neuronal development, axonal and dendritic morphology, synaptic functions, and many other neuronal features. Here we describe a step-by-step process of generating primary neurons from mouse embryonic hippocampi (E17.5/E18.5). Hippocampal neurons generated with this protocol can be plated in different tissue culture dishes according to different experimental aims and can produce a reliable source of pure and differentiated neurons in less than one week. This protocol covers all the steps necessary for the preparation, culture and characterization of the neuronal culture, including the illustration of dissection instruments, surgical procedure for embryos’ isolation, culturing conditions and ... [摘要]  [摘要] 原代培养小鼠海马神经元是一种非常有用的体外模型用于研究神经元的发育,轴突和树突的形态,突触功能,以及许多其他神经元的特征。这里我们描述了从小鼠胚胎海马(E17.5/E18.5)产生初级神经元的一步一步的过程。根据不同的实验目的,用该方法产生的海马神经元可以在不同的组织培养皿中进行培养,并能在不到一周的时间内产生一个可靠的来源。该方案涵盖了神经元培养物的制备、培养和鉴定的所有必要步骤,包括解剖器械的说明、胚胎分离的手术程序、培养条件以及培养物纯度和分化的评估。通过分析培养6天时的钙显像动力学来评估神经元的活性。

[背景] 海马体是一个非常典型的大脑结构,对重要的大脑功能如记忆、空间导航、情绪记忆和学习至关重要。从解剖学上讲,小鼠海马体有一个清晰的C形结构,很容易定位和分离。在细胞水平上,它主要由锥体细胞组成,与其他脑区相比,中间神经元和胶质细胞较少(Kaech和Banker,2006)。因此,海马体是从野生型或基因工程小鼠模型中产生高纯度原代神经元培养物的理想区域,可用于疾病建模或研究神经元功能的多个方面,如突触传递和电生理特性、对神经毒性的敏感性,分化与衰老(;;;;)。Busche,2018Koyama和Ikegaya,2018Molnar,2011Wu等人,2019Rush等人,2020年
