摘要 肿瘤微环境是指与肿瘤细胞生长、增殖及转移等发生发展过程相关的微环境,它不仅包括肿瘤本身的基质细胞,也与肿瘤细胞所处的细胞外基质有关。胆管癌细胞可以通过协同细胞外基质和基质细胞,分泌与肿瘤有关的调节介质来构建有利于自身的肿瘤微环境。微环境缺氧、外泌体等细胞外基质主要通过释放缺氧诱导因子和大量的免疫抑制因子,激活β-catenin和E-cadherin通路来促进胆管癌的增殖和侵袭性。促炎性细胞因子、胆管癌相关成纤维细胞、慢性炎症细胞、上皮细胞、间充质干细胞、上皮间充质干细胞和肿瘤干细胞等基质细胞则可以通过释放细胞因子,激活基质细胞相互间的多种代谢通路,调控胆管癌细胞的转录、翻译过程,在促进胆管癌细胞增殖、加速血管形成、促进肿瘤侵袭和防止细胞凋亡方面发挥着重要作用。
