Sample preparation and stiffness characterization. (A) The preparation of the coculture samples and the control samples without CMFs. The orange arrows indicate measured locations during the dwell experiments. (B) Loading-velocity-dependent stiffness of PDMS 1:100, 1:40, and 1:20 substrates and the native heart tissues. (C) Loading-velocity-dependent stiffness of the CMFs seeded on PDMS 1:100, 1:40, and 1:20 substrates. Data are shown as the mean ± SD (∗, ∗∗, and # indicate statistically significant difference with p < 0.0001, p < 0.005, and p < 0.05, respectively); n = 3 with ∼390 data points for each sample condition.
