摘要:

乳腺肿瘤干细胞(breast cancer stem cellsBCSCs)是乳腺癌中具有干细胞特征的细胞亚群,具有自我更新、多向分化和高度的肿瘤驱动能力。研究表明,BCSCs在乳腺癌发生、发展及耐药过程中发挥着关键作用,因此,深入揭示BCSCs的生物学特性与调控机制是突破乳腺癌治疗难题的重要途径。本综述系统总结了BCSCs表面标志物鉴定、与肿瘤复发与转移的关系、关键调控信号网络,以及其在耐药性中的作用机制同时探讨了基于BCSCs异质性和动态调控节点的靶向治疗策略,展望了未来精准治疗乳腺癌的潜在方向,为相关药物研发提供理论支持和新颖依据。

Abstract:

Breast tumor stem cells (BCSCs) represent a distinctive subpopulation within breast cancer that exhibit stem cell-like characteristics, including self-renewal capability and multipotent differentiation. They are recognized as the central drivers of tumor initiation, progression, metastasis, and drug resistance. In-depth investigation of BCSCs represents a crucial avenue for overcoming the current therapeutic limitations in breast cancer.This review comprehensively summarizes recent advances in BCSCs-related research, focusing on key areas such as surface marker identification, mechanisms underlying tumor recurrence and metastasis, core regulatory signaling networks, and therapy resistance. Furthermore, it discusses potential clinical strategies targeting BCSCs, and explores future directions for precision medicine based on hetogeneity and dynamic regulation of BCSCs. These insights provide important theoretical foundations for the development of targeted therapies against breast cancer.
