FIG. 6. — Underlying relationships in microtissue mechanics. The k₁ and k₂ stress relaxation spring constants were linearly coupled throughout an assortment of pharmacological treatments and step lengths (a) (linear regression; P < 0.001; R² = 0.94). Likewise, the amplitude of stress relaxation was coupled to the amplitude of stress recovery (b) (linear regression; P < 0.001; R² = 0.92).
