Cancer stem cells (CSCs) represent a small subpopulation of cells found within tumors that exhibit properties of self-renewal, like normal stem cells. CSCs have been defined as a crucial factor involved in driving cancer relapse, chemoresistance and metastasis. Prominin-1 (CD133) is one of the most well-characterized markers of CSCs in various tumor types, including hepatocellular carcinoma (HCC). CD133+ cells have been demonstrated to be involved in metastasis, tumorigenesis, tumor recurrence, and resistance to treatment in HCC. CD133-related clinical prognosis prediction, and targeted therapy have highlighted the clinical significance of CD133 in HCC. However, there remains controversy over the role of CD133 in experimental and clinical research involving HCC. In this article, we summarize the fundamental cell biology of CD133 in HCC cells and discuss the important characteristics of CD133+ in HCC cells. Furthermore, the prognostic value of CD133, and therapeutic strategies for its targeting in HCC, is also reviewed.
癌症干细胞 (CSCs) 是肿瘤内发现的一小部分细胞,它们具有自我更新的特性,就像正常干细胞一样。CSCs 被定义为驱动癌症复发、化疗耐药和转移的关键因素。Prominin-1(CD133)是各种肿瘤类型中 CSCs 的最典型标志物之一,包括肝细胞癌 (HCC)。已经证明 CD133+细胞参与 HCC 的转移、肿瘤发生、肿瘤复发和对治疗的耐药性。CD133 相关的临床预后预测和靶向治疗突出了 CD133 在 HCC 中的临床意义。然而,在涉及 HCC 的实验和临床研究中,CD133 的作用仍存在争议。在本文中,我们总结了 CD133 在 HCC 细胞中的基本细胞生物学特性,并讨论了 CD133+在 HCC 细胞中的重要特征。此外,还回顾了 CD133 的预后价值及其在 HCC 中的靶向治疗策略。
