Cell and collagen matrix contributions to the microtissues’ mechanical properties under dynamic loading. (A) Phase contrast and live cell labeled (CellTracker Green) images of microtissues before and during stretch. (B) Time course measurement of normalized microtissue elastic modulus. p< 0.001 between all experimental conditions and p = 0.48 between experimental conditions excluding increased elastic modulus of normal tissue by one-way ANOVA test. Sample sizes: normal tissue, n = 13; n = 6 for all other conditions. All data are presented as Mean ± S.D.
