(a) Aortic rings stretched until a calculated transmural pressure of 13.3 kPa (100 mmHg) was attained (dashed line) showed that transmural pressure is lower in aorta from Acta2−/− mice compared with WT. (b) Thoracic aortic rings were sequentially stretched to elicit 4 mN increases in tension (see inset). Stress relaxation was significantly reduced at low tension in aorta from Acta2−/− mice compared with WT mice, while no significant difference was measured at tension values above 10 mN (n = 4 per group). Data shown as mean ± SD. *Significance was evaluated at P < 0.05.
