896-转移性乳腺癌多模态单细胞与空间图谱

from 聊聊Sci

这项研究通过构建人类肿瘤图谱网络(HTAN)的一部分,利用多种单细胞、单细胞核测序以及空间表达技术,绘制了转移性乳腺癌的分子与细胞空间图谱。研究团队对来自60名患者的67份活检样本进行了深度分析,涵盖了9个不同的转移部位,旨在系统评估肿瘤微环境的复杂性。通过对比Slide-seq、MERFISH、ExSeq和CODEX等多种空间分析方法,该研究为不同技术在临床样本中的应用效能提供了重要参考。分析结果揭示了癌细胞表达模式具有极强的患者特异性,且这种特征在疾病演变和部位转移过程中保持相对稳定。此外,研究还识别了与免疫细胞浸润和上皮-间充质转化相关的空间表型,展示了这些多模态图谱在发现临床相关生物标志物方面的潜力。这一成果为理解转移性乳腺癌的细胞间相互作用及精准治疗方案的制定提供了数据支持。References:Klughammer J, Abravanel D L, Segerstolpe Å, et al.
