令人信服的证据拓宽了我们对肿瘤作为一个共同祖先的高度异质性群体的理解。在这篇综述中,我们描绘了肿瘤发生,肿瘤进展,自我播种和转移的各个阶段,类似于昆虫社会的超有机体来描述肿瘤作为一个功能性“种姓”系统的高度复杂的结构。“因此,我们提出了一个模型,其中克隆扩增和遗传改变的累积获得产生肿瘤隔室,每个隔室都具有不同的特征,因此具有不同的功能,这些功能相互合作,建立临床上明显的肿瘤。这种功能区室模型也提示了肿瘤干细胞小生境自我构建的机制。因此,将肿瘤视为一个超有机体将提供对其功能区室化的系统洞察,甚至可能具有临床意义。
Compelling evidence broadens our understanding of tumors as highly heterogeneous populations derived from one common progenitor. In this review we portray various stages of tumorigenesis, tumor progression, self-seeding and metastasis in analogy to the superorganisms of insect societies to exemplify the highly complex architecture of a neoplasm as a system of functional "castes." Accordingly, we propose a model in which clonal expansion and cumulative acquisition of genetic alterations produce tumor compartments each equipped with distinct traits and thus distinct functions that cooperate to establish clinically apparent tumors. This functional compartment model also suggests mechanisms for the self-construction of tumor stem cell niches. Thus, thinking of a tumor as a superorganism will provide systemic insight into its functional compartmentalization and may even have clinical implications.
