所有细胞都存在于三维微环境中,在这个环境中,它们暴露于机械和物理线索。这些线索可以通过从纳米尺度水平到组织水平的机械转导的扰动而被破坏,这损害了张力稳态以促进诸如心血管疾病和癌症的病理。这种扰动的机制表明,细胞外微环境和细胞功能之间存在复杂的相互作用。此外,细胞外基质的改变可以引起张力稳态的持续破坏,使其成为一种基于机械的记忆储存装置,可以使疾病永久存在或恢复正常的组织行为。
All cells exist within the context of a three-dimensional microenvironment in which they are exposed to mechanical and physical cues. These cues can be disrupted through perturbations to mechanotransduction, from the nanoscale-level to the tissue-level, which compromises tensional homeostasis to promote pathologies such as cardiovascular disease and cancer. The mechanisms of such perturbations suggest that a complex interplay exists between the extracellular microenvironment and cellular function. Furthermore, sustained disruptions in tensional homeostasis can be caused by alterations in the extracellular matrix, allowing it to serve as a mechanically based memory-storage device that can perpetuate a disease or restore normal tissue behaviour.
