1380-SPACE-seq:整合空间转录组与谱系追踪技术

from 聊聊Sci

SPACE-seq 是一种创新性技术,通过将 CRISPR 条形码(DARLIN) 与 空间转录组学(Slide-seqV2) 相结合,实现了在完整组织内同步追踪细胞的谱系起源、转录状态与空间位置。研究人员利用该技术揭示了肝癌(iCCA)中克隆相关肿瘤细胞的表型多样性,并发现肿瘤与基质细胞(如星状细胞)之间的跨空间双向通讯。此外,通过构建大脑发育的 3D 谱系图谱,该研究界定了海马体等区域早期祖细胞的克隆边界与对称发育模式。实验还进一步验证了SELENOP 蛋白具有抑制肝脏纤维化和减轻肿瘤负担的关键功能。总之,SPACE-seq 为探索复杂组织在发育与疾病过程中的谱系动态和空间组织逻辑提供了强大工具。References:Jia Y, Sun D, Weir J A, et al.
