901-早期大肠癌癌胎塑性与成纤维细胞空间重塑

from 聊聊Sci

该研究探讨了结直肠癌(CRC)早期演变中,癌细胞如何获得与转移相关的肿瘤胎儿可塑性。通过对早期T1阶段肿瘤的空间转录组学和单细胞测序分析,研究发现这些具有转移潜能的细胞状态在入侵发生之初便已普遍存在,而非晚期特有。类器官模型和全基因组测序证明,这种表型差异并非由细胞内部的基因突变驱动。相反,这种转变是由肿瘤微环境引导的,特别是位于入侵边缘的滋养细胞样癌症相关成纤维细胞(CAFs)诱导了癌细胞向胎儿态转化。此外,虽然这种可塑性是转移的必要条件,但最终的转移成功还取决于免疫逃逸等后续瓶颈。总之,这项工作强调了基质相互作用在决定结直肠癌早期恶化中的核心作用。References:Buissant des Amorie J R, Hageman J H, Brunner S R, et al.
