[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

已经制定了许多协议,通过与神经胶质喂食器共同培养神经元来产生皮层和海马神经元(Kaech和Banker,2006),描述了用水凝胶微纤维封装的星形胶质细胞的三维神经元培养系统(Kim等人,2020年),长期向培养基中补充生长因子神经元培养(Ray ...

In vitro Differentiation of Murine Innate Lymphoid Cells from Common Lymphoid Progenitor Cells

[Abstract]  Subtypes of innate lymphoid cells (ILC), defined based on their cytokine secretion profiles and transcription factor expression, are important for host protection from pathogens and maintaining tissue homeostasis. ILCs develop from common lymphoid progenitors (CLP) in the bone marrow. Using the methods described here, we have previously shown that loss of the transcriptional regulator TOX (Thymocyte-selection associated HMG-box protein) leads to specific changes in ILC development and differentiation. Here, we describe how to obtain ILCs from in vivo isolated CLP grown in vitro. [摘要]  先天淋巴细胞(ILC)的亚型,基于其细胞因子分泌谱和转录因子表达来定义,对于宿主保护免于病原体和维持组织内稳态是重要的。 ILC从骨髓中的普通淋巴祖细胞(CLP)发展而来。 使用本文所述的方法,我们以前显示转录调节器TOX(胸腺细胞选择相关的HMG框蛋白)的损失导致ILC发展和分化的具体变化。 在这里,我们描述了如何从体内分离的CLP获得ILC。
