癌细胞的局部微环境或生态位在癌症发展中起着重要作用。小生境的主要组成部分是细胞外基质(ECM),一个复杂的网络的大分子具有独特的物理,生物化学和生物力学特性。虽然在胚胎发育和器官稳态期间受到严格控制,但ECM通常被解除管制,并在癌症等疾病中变得紊乱。异常ECM通过直接促进细胞转化和转移影响癌症进展。然而,重要的是,ECM异常也解除了基质细胞的行为,促进肿瘤相关的血管生成和炎症,从而导致肿瘤发生微环境的产生。了解ECM成分和拓扑结构如何维持以及它们的失调如何影响癌症进展可能有助于通过靶向肿瘤小生境开发新的治疗干预措施。
The local microenvironment, or niche, of a cancer cell plays important roles in cancer development. A major component of the niche is the extracellular matrix (ECM), a complex network of macromolecules with distinctive physical, biochemical, and biomechanical properties. Although tightly controlled during embryonic development and organ homeostasis, the ECM is commonly deregulated and becomes disorganized in diseases such as cancer. Abnormal ECM affects cancer progression by directly promoting cellular transformation and metastasis. Importantly, however, ECM anomalies also deregulate behavior of stromal cells, facilitate tumor-associated angiogenesis and inflammation, and thus lead to generation of a tumorigenic microenvironment. Understanding how ECM composition and topography are maintained and how their deregulation influences cancer progression may help develop new therapeutic interventions by targeting the tumor niche.
