实体瘤的特征在于异常的基质,其有助于肿瘤微环境中生物力学异常的发展。特别是,这些异常包括基质硬度的增加和肿瘤内部固体应力的积累。到目前为止,还没有明确定义基质硬度和实体应力是否彼此密切相关,或者它们在肿瘤进展中具有不同的作用。此外,虽然与固体应力的贡献相比,刚度对肿瘤进展的影响被广泛研究,但重要的是要确定肿瘤发生和转移异常的生物学结果。在这篇综述中,我们讨论了这些参数是如何在肿瘤生长过程中演变的,以及这些参数是如何相互影响的。我们进一步审查了基质硬度和固体应力对癌症和基质细胞的增殖和转移潜力的影响,并总结了体外实验装置,已被设计用于研究这些参数的个人贡献。
Solid tumors are characterized by an abnormal stroma that contributes to the development of biomechanical abnormalities in the tumor microenvironment. In particular, these abnormalities include an increase in matrix stiffness and an accumulation of solid stress in the tumor interior. So far, it is not clearly defined whether matrix stiffness and solid stress are strongly related to each other or they have distinct roles in tumor progression. Moreover, while the effects of stiffness on tumor progression are extensively studied compared to the contribution of solid stress, it is important to ascertain the biological outcomes of both abnormalities in tumorigenesis and metastasis. In this review, we discuss how each of these parameters is evolved during tumor growth and how these parameters are influenced by each other. We further review the effects of matrix stiffness and solid stress on the proliferative and metastatic potential of cancer and stromal cells and summarize the in vitro experimental setups that have been designed to study the individual contribution of these parameters.
