1281-基于hiPS细胞的EMT全景研究模型

from 聊聊Sci

这项研究利用人类诱导多能干细胞(hiPS)建立了一个标准化实验平台,旨在从多维度解析上皮-间质转化(EMT)的动态过程。研究人员通过构建二维菌落和三维类腔体两种不同的细胞培养几何结构,对比观察了细胞在功能、分子及组织层面的状态切换。实验发现,三维环境下的基底膜完整性对细胞迁移的起始时间具有显著的物理限制作用,导致其迁移晚于二维环境。通过对多种EMT标志物(如E-钙粘蛋白和Brachyury)进行实时活细胞成像和定量分析,该研究揭示了细胞几何形状对分子表达轨迹的特异性影响。总体而言,该研究为深入理解人类早期发育和疾病中的细胞状态转变提供了一套整合了影像分析、数据集与操作工具的开放性框架。References:Hookway C, Borensztejn A, Harris L K, et al.
