在这里,我们描述了一个平台,该平台允许对植入小鼠眼前房的肝球体进行非侵入 性体内 成像。工作流程涵盖从原代肝细胞生成球状体到移植到小鼠眼中,以及通过共聚焦显微镜以细胞分辨率进行 体内 成像。

在我们小组中,我们使用小鼠眼的前房作为肝类固醇体内和非侵入性成像的移植部位。这个新建立的成像平台将为研究人员提供一个独特的工具,并在基础和临床前研究中扩大我们对肝脏生理学和病理学的理解。在生物医学研究中,我们依靠细胞过程的可视化来理解疾病机制,而肝脏研究领域目前缺乏体内高分辨率成像的方法,其中肝细胞可以随着时间的推移进行纵向监测。

与活体肝脏成像相比,我们的技术是非侵入性的,肝细胞可以在多次成像过程中重复成像,使我们能够以单细胞分辨率监测肝功能以应对不同的挑战。通过我们的平台,肝脏类固醇可以在眼睛中存活数月,并且随着时间的推移,可以对同一只受体小鼠进行非侵入性成像。这样可以减少我们使用的实验动物的数量,同时提高体内数据的质量。

在过去的十年中,我们小组已将眼成像平台发展成为强大的研究工具。它最初是为胰腺孔的成像而设计的,但现在已经适应了肝脏类固醇,并有可能扩展到其他器官和研究领域。
