摘要: 乳腺癌是一种具有异质性的全身性疾病,其微环境主要由肿瘤细胞及多种非肿瘤细胞组成。其中间充质干细胞在肿瘤的发生发展中发挥着重要作用。间充质干细胞可直接通过缝隙连接、膜受体和微管或间接通过可溶性分子与肿瘤细胞及其微环境相互作用。肿瘤相关成纤维细胞来源于癌旁成纤维细胞或间充质干细胞,在肿瘤耐药过程中发挥重要作用。在乳腺癌中,肿瘤干细胞与其所处微环境处于动态平衡状态,其表型受细胞因子的密切调控。间质细胞通过与乳腺癌细胞的相互作用,进而对其生物学特性产生重要影响。另外,间质细胞可改变肿瘤细胞对化疗药物的敏感性,进而使其产生耐药。因此,解决肿瘤间质细胞介导的化疗耐药是成功治疗中晚期乳癌的关键。本文主要阐述了间质细胞在乳腺癌微环境中介导化疗耐药的研究进展。

Abstract: Breast cancer is a heterogeneous systemic disease.Its microenvironment is mainly composed of tumor cells and a variety of non-tumor cells.Among them,mesenchymal stem cells(MSCs)play an important role in tumorigenesis and development.MSCs can interact with tumor cells and their microenvironment directly through gap junctions,membrane receptors and microtubules,or indirectly through soluble molecules.Tumor-associated fibroblasts(CAFs)are derived from adjacent cancer fibroblasts or MSCs,and play an important role in tumor drug resistance.In breast cancer,tumor stem cells and their microenvironment are in a dynamic equilibrium state,and their phenotype is closely regulated by cytokines.Interstitial cells have an important effect on their biological characteristics through their interaction with breast cancer cells.In addition,interstitial cells can change the sensitivity of tumor cells to chemotherapeutic drugs,which in turn make them resistant.Therefore,addressing tumor stromal cell-mediated resistance to chemotherapy is the key to successful treatment of advanced breast cancer.This article mainly describes the research progress of stromal cells in the microenvironment mediated chemotherapy resistance of breast cancer.
