[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。
