Figure 6. Biomechanical properties.

(A) compressive relaxation modulus at 10% strain (B) compressive instantaneous modulus at 10% strain (C) circumferential Young's tensile modulus (D) radial Young's tensile modulus. All mechanical properties were significantly enhanced by chemical stimulation and D1 mechanical stimulation. All data are presented as mean ± s.d. Statistically significant differences are present when a common letter is not shared between levels of a factor or by individual groups. For mechanical stimulation, the characters α and β are used. For chemical stimulation, letters A and B are used. For comparisons among the 6 treatment groups, the letters a, b, c, d, and e are used.
