[Abstract] Transplantation in mouse brain slices is a powerful tool in order to study axon targeting and migrational events during development. Taking advantage of donors and recipients belonging to different genotypes, this technique allows researchers to assess the contribution of donor and/or recipient tissue by performing various combinations and to study cell-autonomous functions or effects that are influenced by the recipient’s environment (Bastakis, et al., 2015). Here we describe the transplantation procedure on sagittal brain slices containing olfactory bulb (OB). Specifically, we have ...
[摘要] 小鼠脑切片中的移植是一个强大的工具，以便研究轴突靶向和发展过程中的迁移事件。 利用属于不同基因型的供体和受体，该技术允许研究人员通过进行各种组合来评估供体和/或受体组织的贡献，并研究受受体环境影响的细胞自主功能或效应（Bastakis， em>等人，2015）。 在这里我们描述的矢状大脑切片包含嗅球（OB）的移植程序。 具体来说，我们已经将背侧OB的近端到外皮部分移植到受体切片上的相同区域。 移植的切片可以培养长达3天，之后由于3D中的生长它们的形态被破坏。 这些切片的重新切片允许更详细的免疫组织化学分析。

[Abstract] The neural tube explant culture technique allows in vitro culturing of small pieces of neural tissue isolated from e.g., chick or mouse embryonic tissue in a matrix of collagen for defined periods of time. This method can be used to study the effects of defined molecules on developmental processes such as neural progenitor proliferation and neuronal differentiation and/or survival. Since the explant material can also be prepared from embryonic tissue electroporated with expression vectors, this technique can be adapted to study gene function in the presence of specific ...
[摘要] 神经管外植体培养技术允许在胶原基质中从例如小鸡或小鼠胚胎组织分离的小片神经组织的体外培养定义的时间段。 该方法可用于研究限定分子对发育过程如神经祖细胞增殖和神经元分化和/或存活的影响。 由于外植体材料也可以从用表达载体电穿孔的胚胎组织制备，该技术可以适于在特定环境信号的存在下研究基因功能。 也可以在解剖步骤期间分离神经管的不同区域，允许单独研究神经管的特定区域。 在这里，我们提出了我们已经在几个研究中使用的神经管外植体培养方法（Dias等人，2014; Lek等人，2010; Vallstedt， et al。，2005）。

[Abstract] The intestine, together with skin and blood, belongs to the organs with the highest cell turnover, which makes it a perfect model to study cellular processes, such as proliferation and differentiation. Epithelial cell turnover in intestine is possible due to the presence of intestinal stem cells, which are located at the bottom of the crypt. Here, we recapitulate a detailed protocol for the isolation and culture procedures of primary epithelial intestinal cells in a three - dimensional (3D) in vitro system, described for the first time by Hans Clevers group (Sato et al., ...
[摘要] 肠道与皮肤和血液一起属于具有最高细胞更新的器官，这使得它成为研究细胞过程如增殖和分化的完美模型。由于存在位于隐窝底部的肠干细胞，肠上皮细胞更新是可能的。在这里，我们重述了在三维（3D）体外系统中原发性上皮肠细胞的分离和培养程序的详细方案，首次由Hans Clevers组（Sato > et al。，2009）。这种特定的3D培养物保留肠干细胞，其产生分化的子代，例如杯状细胞。该培养物具有许多应用并且代表研究干细胞生物学，上皮细胞再生和移植研究的有用模型。此外，呈现的3D文化可用于调查肠上皮细胞的屏障功能，以及上皮细胞和基质细胞之间的异型细胞相互作用。
