SHR colon samples are 3 times stiffer than the normotensive WKY controls. A) Steady-state moduli of the WKY (control) and SHR colon samples (n = 5 animals for WKY and n = 4 animals for SHR with 3–4 indentations per animal) are 5.11 ± 1.58 kPa and 18.17 ± 11.45 kPa, respectively. Pooled means for all indentations were significantly different (p < 0.009), and average of means calculated for each animal were also significantly different (p = 0.05) based on the conservative Welch’s t-test. Error bars depict standard deviation. B) After a quasi-infinite time, tissues exhibit distinct steady-state properties during stress-relaxation. Control animals (dashed blue line) show a lower steady-state modulus than the SHR animals (solid orange line). Only a sub-set of the control curves are plotted for clarity but do depict the total range of values measured.
