Storage and loss moduli vs. angular velocity for: a The Maxwell model calculated by eq. 3 for the model parameters: the relaxation time for stress τR1 = 3 min and the viscosity η = 7.3x103Pa min; (This relaxation time corresponds to the order of magnitude of stress relaxation time for cell aggregate uniaxial compression between parallel plates while the viscosity corresponds to the value obtained for epithelial cell aggregate obtained by Marmottant et al. [29].) b The Kelvin-Voigt model calculated by eq. 5 for the model parameters: the elastic modulus Gs = 1 kPa and the viscosity η = 7.3x103Pa min. (The value of the elastic modulus is in the range of the experimental values obtained for soft tissue [30])
