Recent studies have shown that stiffening of the ECM resulting from deposition and crosslinking of collagen may promote invasion and migration of tumor cells. In our previous study, a laser speckle contrast shear wave (SW) imaging system was developed, and a feasibility study on non-invasive, non-superficial and exogenous-tracer-free evaluation of the mechanical property of the 3-D cell matrix was performed. In this report, the system is used to measure the stiffness of 3-D cancer metastasis models. We hypothesize that the developed system can provide temporal and spatial information of the cell matrix during cancer progression related to cancer cell migration and metastasis.[SDGs]SDG3conference paper10.1109/ULTSYM.2017.80924792-s2.0-85039423324https://api.elsevier.com/content/abstract/scopus_id/85039423324
