越来越多的证据支持癌症干细胞(CSC)假说,该假说认为癌症是由一种具有干细胞特性的细胞成分驱动的,包括自我更新、成瘤性和多谱系分化能力。研究人员和肿瘤学家在这个模型中看到了为什么癌症可能如此难以治愈的解释,以及为新的治疗策略提供了一个有希望的基础。鉴于干细胞自我更新和分化的特定特征,这推动了肿瘤的形成并促进了细胞的异质性,设计用于分离和表征CSCs的每个标记和分析都必须进行功能验证。在这篇综述中,我们综述了现有的或有望识别乳腺CSCs的工具和标记物。我们回顾了用于研究乳腺CSC的主要模型,以及它们如何挑战CSC假说。
There is increasing evidence for the "cancer stem cell (CSC) hypothesis", which holds that cancers are driven by a cellular component that has stem cell properties, including self-renewal, tumorigenicity and multi-lineage differentiation capacity. Researchers and oncologists see in this model an explanation as to why cancer may be so difficult to cure, as well as a promising ground for novel therapeutic strategies. Given the specific stem cell features of self-renewal and differentiation, which drive tumorigenesis and contribute to cellular heterogeneity, each marker and assay designed to isolate and characterize CSCs has to be functionally validated. In this review, we survey tools and markers available or promising to identify breast CSCs. We review the main models used to study breast CSCs and how they challenge the CSC hypothesis.
