细胞外基质(ECM)提供调节细胞功能的结构和生化信号。细胞和周围环境之间的良好控制的平衡(即,动态互易性)对于调节ECM架构至关重要。在癌症进展期间,上皮细胞经历遗传改变,其与基质变化(包括ECM重塑)一起扰乱上皮的稳态动力学。间质ECM原纤维的平行组织与致瘤反应相关。在一个新兴的范例中,通过机械力和异常信号传导的连续和渐进的调节被认为是肿瘤相关ECM重塑的原因。在这篇综述中,我们讨论了离散的生物力学和生化机制,这些架构的变化,并强调其特定的相关性,在间充质基质中的ECM的调整。
The extracellular matrix (ECM) provides structural and biochemical signals that regulate cell function. A well-controlled balance between cells and surroundings (i.e., Dynamic Reciprocity) is crucial for regulating ECM architecture. During cancer progression, epithelial cells undergo genetic alterations, which together with stromal changes, including ECM remodeling, disturb the homeostatic dynamics of the epithelium. A parallel organization of stromal ECM fibrils is associated with tumorigenic responses. In an emerging paradigm, continuous and progressive regulation via mechanical forces and aberrant signaling are believed to be responsible for tumor-associated ECM remodeling. In this review, we discuss the discrete biomechanical and biochemical mechanisms that underlie these architectural changes and highlight their particular relevance to the regulation of the alignment of ECM in the mesenchymal stroma.
