930-胶质母细胞瘤的空间架构与细胞通讯图谱

from 聊聊Sci

这篇文章通过整合多达100名患者的单细胞测序与空间转录组数据,深入剖析了人类胶质母细胞瘤(GBM)复杂的肿瘤微环境。研究者识别出四种具有特定细胞组成和基因表达特征的细胞群落(CCs),并重点发现了间充质样(MES-like)肿瘤细胞的两个功能亚型:与缺氧及巨噬细胞相关的MES-Hyp,以及与血管组织相关的MES-Ast。通过轨迹分析和类器官实验,研究证明了肿瘤细胞在缺氧压力下的动态演变进程。此外,研究揭示了驱动单核细胞向特定肿瘤相关巨噬细胞转化的关键转录因子。最后,利用电极片测序(Patch-seq)技术证实了神经元主要与类少突胶质前体细胞形成突触连接。总体而言,该研究构建了GBM的空间组织图谱,为开发新的治疗靶点提供了重要依据。References:Lin J, Chen C, Li S, et al.
