摘要

小鼠的胃形成会导致细胞命运、组织形状和胚胎大小的同步变化。使用可重现的体外系统对剖析协调这些事件的机制至关重要。在这里，我们介绍了一种生成上胚层干细胞三维培养物（3D EpiSCs）的方案，这种培养物以上皮球体的形式生长，模仿了胃排卵期小鼠胚胎上胚层的主要特征。我们介绍了球形细胞的形成、生长和传代步骤，然后进行成像或进一步的下游分析。有关该方案使用和执行的完整细节，请参阅 Sato 等人的文章1。

Protocol for generating a 3D culture of epiblast stem cells.

Mouse gastrulation entails concomitant changes in cell fate, tissue shape, and embryo size. The use of a reproducible in vitro system is crucial for dissecting the mechanisms that coordinate these events. Here, we present a protocol for generating a 3D culture of epiblast stem cells (3D EpiSCs), which grow as epithelial spheroids mimicking key features of the gastrulating mouse embryonic epiblast. We describe steps for spheroid formation, growth, and passaging, followed by imaging or further downstream analyses. For complete details on the use and execution of this protocol, please refer to Sato et al.¹.
