Whole-mount Enteroid Proliferation Staining
[Abstract]  Small intestinal organoids, otherwise known as enteroids, have become an increasingly utilized model for intestinal biology in vitro as they recapitulate the various epithelial cells within the intestinal crypt (Mahe et al., 2013; Sato et al., 2009). Assessment of growth dynamics within these cultures is an important step to understanding how alterations in gene expression, treatment with protective and toxic agents, and genetic mutations alter properties essential for crypt growth and survival as well as the stem cell properties of the individual cells within the ... [摘要]  小肠类器官,也称为肠袢,已经成为越来越多地用于肠道生物学的体外模型,因为它们重现了在肠隐窝内的各种上皮细胞(Mahe等人 ,2013; Sato et al。,2009)。在这些培养物中评估生长动力学是理解基因表达的改变,用保护性和毒性试剂处理以及遗传突变改变隐窝生长和存活所必需的性质以及细胞内单个细胞的干细胞性质的重要步骤地穴。该方案描述了在隐窝内三维的增殖细胞的可视化方法(Barrett等人,2015)。使用EdU掺入的肠衣的整体增殖染色使得研究者能够观察到肠内的所有增殖细胞,而不是如在包埋和切片中所见到的在薄切片中获得生长信息,确保来自干细胞区室的增殖的真实表现到隐窝的终末分化细胞。

Isolation, Culture, and Maintenance of Mouse Intestinal Stem Cells
[Abstract]  In this protocol we describe our modifications to a method to isolate, culture and maintain mouse intestinal stem cells as crypt-villus forming organoids. These cells, isolated either from the small or large intestine, maintain self-renewal and multilineage differentiation potential over time. This provides investigators a tool to culture wild type or transformed intestinal epithelium, and a robust assay for stem cell tissue homeostasis in vitro. [摘要]  在这个协议,我们描述我们修改分离,培养和维持鼠肠干细胞作为隐窝 - 绒毛形成类器官的方法。 从小肠或大肠分离的这些细胞随时间保持自我更新和多向分化潜能。 这为研究人员提供了培养野生型或转化的肠上皮的工具,以及用于体外干细胞组织稳态的稳健试验。
