摘要

癌症干细胞(CSCs)真的起源于异常的人类干细胞(hSCs)吗?癌症是多细胞生物中细胞分化的疾病,还是在生命的进化史中有更深的根源?在各种组织和器官的肿瘤以及已建立的肿瘤细胞系中发现了癌症干细胞。与正常干细胞一样,csc具有自我更新、静止和细胞分化的能力。它们侵入其他组织,引起继发性肿瘤、转移和癌症复发。CSCs表达胚胎干细胞标志物OCT4、NANOG、SOX2和YAP[1]。所有这些发现使以前的癌症研究人员假设csc来自缺陷的人类干细胞(hsc)。一些癌症研究人员认为癌症是一种“干细胞疾病”。

Cancer Stem Cells and the Unicellular Life Cycle of Cancer
Does cancer stem cells (CSCs) really originate from abnormal human stem cells (hSCs)? And is cancer a disease of cell differentiation in multicellular organisms or does it have deeper roots in the evolutionary history of life? Cancer stem cells were found in tumors of various tissues and organs as well as in established tumor cell lines. Like normal stem cells, CSCs are capable of self-renewal, quiescence, and cell differentiation. They invade other tissues and cause secondary tumors, metastases and cancer recurrence. CSCs express the embryonic stem cell markers OCT4, NANOG, SOX2 and YAP [1]. All these findings led previous cancer researchers to the assumption that CSCs arise from deficient human stem cells (hSCs). Some cancer researchers regarded cancer as a “stem cell disease” [2].
