乳腺肿瘤中的所有肿瘤细胞是否具有相同的增殖和维持肿瘤生长的潜力,或者是否存在分层组织,目前存在广泛争议。后一种理论的证据主要基于移植的肿瘤细胞在免疫系统受损的小鼠中是否能够产生可检测到的肿瘤;然而,这种测定法最近是否能准确反映未受干扰的肿瘤中的细胞行为存在争议。谱系追踪实验最近表明存在一小群细胞,称为癌症干细胞(CSC),它们维持并促进鳞状皮肤肿瘤和肠腺瘤的生长。然而,这些研究中使用的谱系追踪技术提供静态图像,缺乏研究干细胞特性是否可以获得或丢失的能力,这一过程被称为干细胞可塑性。在这里,通过活体谱系追踪,我们首次报告了未受干扰的乳腺肿瘤中 CSC 的存在,并证明了 CSC 的可塑性。我们的数据表明,在乳腺肿瘤生长过程中,现有的 CSC 消失,新的 CSC 形成,这说明了这些细胞的动态性质。干细胞 2013;31:602–606
It is widely debated whether all tumor cells in mammary tumors have the same potential to propagate and maintain tumor growth or whether there is a hierarchical organization. Evidence for the latter theory is mainly based on the ability or failure of transplanted tumor cells to produce detectable tumors in mice with compromised immune systems; however, this assay has lately been disputed to accurately reflect cell behavior in unperturbed tumors. Lineage tracing experiments have recently shown the existence of a small population of cells, referred to as cancer stem cells (CSCs), that maintains and provides growth of squamous skin tumors and intestinal adenomas. However, the lineage tracing techniques used in these studies provide static images and lack the ability to study whether stem cell properties can be obtained or lost, a process referred to as stem cell plasticity. Here, by intravital lineage tracing, we report for the first time the existence of CSCs in unperturbed mammary tumors and demonstrate CSC plasticity. Our data indicate that existing CSCs disappear and new CSCs form during mammary tumor growth, illustrating the dynamic nature of these cells. Stem Cells 2013;31:602–606
