Summary

存在于大多数生物体中的昼夜节律调节着生物过程的时间组织。3D类器官最近作为一种生理学相关的 体外 模型出现。该协议描述了使用生物发光报告基因来观察类器官中的昼夜节律,从而能够对多细胞系统中的昼夜节律进行 体外 研究。

Transcript

我们目前的研究范围是研究昼夜节律在肠上皮细胞增殖和分化中的作用。我们正试图确定生物钟是否调节细胞增殖和肠道干细胞的分化。该协议提供了一种使用生物发光测定法进行三维类器官昼夜节律研究的实时监测方法。

与在传统的二维细胞培养中进行生物发光测定不同,这种方法使我们能够在生理学更相关的类器官模型中研究昼夜节律及其功能。我们的研究结果表明,在富含干细胞的条件下,昼夜节律被打乱,同时在分化的人类肠道类器官中表现出强大的昼夜节律振荡,这表明生物钟机制从干细胞到分化细胞的重塑。使用患者来源的类器官与昼夜节律生物发光报告基因将帮助我们提高对外周器官和不同疾病状态的昼夜节律的理解。
