[Abstract] The tri-dimensional culture, initially described by Sato et al. (2009) in order to isolate and characterize epithelial stem cells of the adult small intestine, has been subsequently adapted to many different organs. One of the first examples was the isolation and culture of antral stem cells by Barker et al. (2010), who efficiently generated organoids that recapitulate the mature pyloric epithelium in vitro. This ex vivo approach is suitable and promising to study gastric function in homeostasis as well as in disease. We have adapted Barker’s protocol to compare homeostatic and regenerating tissues and here, we meticulously describe, step by step, the isolation and culture of antral glands as well as the isolation of single cells from antral glands that ...
[摘要] 为了分离和表征成年小肠的上皮干细胞，最初由Sato等人（2009）描述的三维培养物已经随后适应于许多不同的器官。其中一个例子是Barker等人（2010）分离和培养窦性干细胞，他们有效地产生了在体外重现成熟幽门上皮的组织细胞。这种“离体”方法是适合的，并且有希望研究体内平衡和疾病中的胃功能。我们已经调整了Barker的方案来比较稳态和再生组织，这里，我们一步一步地仔细地描述了窦腺的分离和培养，以及从细胞分选后可能用于培养的窦腺中分离单细胞一个例子（Fernandez Vallone等人，2016）。
背景来自腺体的小鼠成体干细胞可以在3D matrigel中离体生长，作为“迷你腺体”无限期（Barker等人，2010） 。与EGF，Noggin和R-spondin 1存在下生长的小鼠成年小肠的干细胞相比，胃干细胞需要进一步补充Fgf10，胃泌素，Wnt3a和更高浓度的R-螺旋菌素1（称为作为ENRFGW）获得生产性文化。直到最近，在干细胞消融后，在离体培养系统中成体再生窦腺是否生长，如果是这样，仍然是未知的。使用本方案，证明了内源性和再生的腺体在接种时不会类似地生长并且表现出不同的生长培养要求。

[Abstract] The isolation and primary culture of cells from human endometrial biopsies provides valuable experimental material for reproductive and gynaecological research. Whole endometrial biopsies are collected from consenting women and digested with collagenase and DNase I to dissociate cells from the extracellular matrix. Cell populations are then isolated through culturing, filtering and magnetic separation using cell-surface antigen markers. Here we provide a comprehensive protocol on how to isolate and culture individual cell types from whole endometrial tissues for use in in vitro experiments.
[摘要] 从人子宫内膜活组织检查中分离和原代培养细胞为生殖和妇科研究提供了有价值的实验材料。从同意的妇女收集完整的子宫内膜活检组织并用胶原酶和DNA酶I消化以从细胞外基质中分离细胞。然后通过使用细胞表面抗原标记物的培养，过滤和磁性分离来分离细胞群。在这里，我们提供了如何从整个子宫内膜组织分离和培养个体细胞类型以用于体外实验的全面方案。
[背景] 人子宫内膜是子宫内层最粘的层。其由柱状上皮和基础基质层组成，其经历循环再生，生长和响应于循环激素的转化。子宫内膜衬里分化为腺分泌表型为囊胚植入和成功怀孕提供了一个好客的环境。在没有怀孕这个层脱落，导致月经。从人子宫内膜活组织检查中分离和培养细胞允许在体外功能评估和与患者结果相关的细胞特征的研究。子宫内膜细胞的分离和培养是研究妇科和产科医学的许多方面的非常宝贵的研究模型，包括不孕，植入失败，复发性流产和月经紊乱。全人子宫内膜活检包含人子宫内膜基质细胞（HESCs），腔和子宫内膜上皮细胞（HEEC），红细胞和免疫细胞的混合群体。 ...

[Abstract] The real time visualisation of fluorescently tagged proteins in live cells using ever more sophisticated microscopes has greatly increased our understanding of the dynamics of key proteins during fundamental physiological processes such as cell locomotion, chemotaxis, cell division and membrane trafficking. In addition the fractionation of cells and isolation of organelles or known compartments can often verify any subcellular localisation and the use of tagged proteins as bait for the immunoprecipitation of material from cell fractions can identify specific binding partners and multiprotein complexes thereby helping assign a function to the tagged protein. We have successfully applied these techniques to the Dictyostelium discoideum protein TSPOON that is part of an ancient ...
[摘要] 使用更复杂的显微镜，活细胞中荧光标记的蛋白质的实时可视化大大增加了我们对基本生理过程如细胞运动，趋化性，细胞分裂和膜运输过程中关键蛋白质动力学的了解。此外，细胞的分级和分离细胞器或已知的隔室通常可以验证任何亚细胞定位，并且使用标记的蛋白质作为诱饵用于来自细胞部分的物质的免疫沉淀可以鉴定特异性结合配偶体和多蛋白复合物，从而有助于赋予功能标记蛋白。我们已经成功地将这些技术应用于作为古代异构六聚体膜转运复合物的一部分的盘基网柄菌discoideum蛋白TSPOON（Hirst等，2013）。 ...
