WebMay 2, 2016 · Gels formed from ECM protein biopolymers such as collagen or fibrin are commonly used for 3D cell culture models of tissue. One of the most striking features of these gels is that they exhibit nonlinear elasticity, undergoing strain stiffening. WebMay 6, 2015 · The technique is based on a depth sensing nano-indentation tester to measure the thickness and elasticity of collagen gels containing stimulated fibroblasts and a microscopy imaging system to estimate the gel area. In parallel, a simple theoretical model has been developed to calculate cell contraction force based on the measured … WebJan 1, 2013 · The wet substrate was maintained at the level of a water bath to allow for fluid flow. As shown in Fig. 1 A, an impermeable polystyrene tube was used to laterally support the gel, inhibiting radial fluid flow.
