癌症干细胞(CSC),其中包括一小部分的癌细胞,被认为是构成大多数人类肿瘤的起源。相当大的努力集中在鉴定多种肿瘤类型中的CSC和鉴定将CSC与正常组织干细胞区分开的遗传特征上。许多研究还表明,CSC是转移的基础。然而,CSC是播散性转移的基础的实验证据已经落后于CSC的概念结构。然而,最近的研究表明,CSC可能直接或间接地促进转移的产生。此外,CSC的异质性可能在很大程度上负责转移的相当大的复杂性和器官特异性。在这篇综述中,我们讨论了CSCs在转移中的作用及其作为治疗靶点的潜力。
Cancer stem cells (CSCs), which comprise a small fraction of cancer cells, are believed to constitute the origin of most human tumors. Considerable effort has been focused on identifying CSCs in multiple tumor types and identifying genetic signatures that distinguish CSCs from normal tissue stem cells. Many studies also suggest that CSCs serve as the basis of metastases. Yet, experimental evidence that CSCs are the basis of disseminated metastases has lagged behind the conceptual construct of CSCs. Recent work, however, has demonstrated that CSCs may directly or indirectly contribute to the generation of metastasis. Moreover, CSC heterogeneity may be largely responsible for the considerable complexity and organ specificity of metastases. In this review, we discuss the role of CSCs in metastasis and their potential as therapeutic targets.
