Fig. 5.
(A) Time-dependent bulk modulus values (p=0.1439) of the cell-ECM inclusion as determined from the composite spheres model (Eq. (5)) where the assumed Poisson ratios are νconstruct=0.4 and νscaffold=0.4. Mean ± standard error (SE) values are shown for n=4 samples per culture time point. (B) Construct modulus (K) including the variability due to the influence of νconstruct=0.1 or 0.4 (mean ± SE). There is a 95% confidence interval of the cell-ECM bulk modulus (Kc-m) due to iterative variations in νconstruct=0.1 or 0.4 and νscaffold=0.1 or 0.4 as indicated by the gray bar, smoothed through time.
