[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 ...

Whole Mammary Gland Transplantation in Mice Protocol

[Abstract]  Whole Mammary Gland Transplantation involves transplanting an excised mammary gland into another, more suitable host. This method can be used to extend the life of a mammary gland past the mouse’s life span by transplanting the mammary gland of an older mouse into a young healthy mouse. As you can see in the video below (Video 1), by attaching it to the abdomen of the mouse, the gland will receive a steady blood supply and both epithelial and stromal cells will remain viable for up to one year. Although this method is not used often, it has been part of several experiments including determining whether the stroma or epithelium is the primary target in chemically induced mouse mammary tumorigenesis (Medina and Kittrell, 2005). To monitor transplants, palpate every week for tumor formation. ... [摘要]  全乳腺移植涉及将切除的乳腺移植到另一个更合适的宿主中。该方法可用于通过将老鼠的乳腺移植到年轻的健康小鼠中来延长乳腺的寿命,超过老鼠的寿命。在下面的视频(视频1)中可以看到,通过将其附加到鼠标的腹部,腺体将获得稳定的血液供应,并且上皮细胞和基质细胞将保持活力长达一年。虽然这种方法不经常使用,但它已经是几个实验的一部分,包括确定基质或上皮是化学诱导的小鼠乳腺肿瘤发生的主要靶标(Medina和Kittrell,2005)。为了监测移植物,每周触诊肿瘤形成。移植的乳腺也可以每8-10周连续传播一次。将移植腺保持在同一只老鼠不超过一年。

[Abstract]  Primary microglia, in either mono-culture or co-culture with neurons or astrocytes, are a powerful tool for studying mechanisms underlying microglial inflammatory responses and cell type-specific interactions in the central nervous system (CNS). This protocol provides the details of how to prepare high purity primary microglia from newborn mouse pups. The overall steps include brain cell dissociation, mixed glial cell culture, and microglia isolation. [摘要]  单细胞培养或与神经元或星形胶质细胞共培养的原代小胶质细胞是研究中枢神经系统(CNS)中小胶质细胞炎症反应和细胞类型特异性相互作用的机制的有力工具。 该方案提供了如何从新生小鼠幼崽准备高纯度小胶质细胞的细节。 总体步骤包括脑细胞解离,混合胶质细胞培养和小胶质细胞分离。
【背景】近年来,神经炎症已成为神经科学研究的热点领域。在各种神经系统疾病患者的脑中观察到炎症反应,如胶质细胞激活和细胞因子上调(Fan等,2015; Koshimori等,2015; Garden and Campbell,2016)。神经炎症不仅被认为是脑内病理变化的结果,而且也是疾病进展的贡献者(Schwartz等,2013)。此外,炎症途径的生理功能,其重要性以前被低估,正在被揭示为令人惊讶的多才多艺。例如,补体信号通路的激活通常在神经系统疾病中的中枢神经系统(CNS)中被观察到,并被怀疑参与疾病病理生理学(Michailidou等人,2015; Loeffler等人,2008)。现在我们知道它也在突触细化发育调控中发挥重要作用(Stevens et ...
