Key result
In C57bl/6 mice, residual circumferential strain led to uniform transmural strain of the aorta at pressures of 60-120 mmHg, with 85% of volume compliance located in the thoracic aorta.

Does not support clinical aortic assessment changes; extends baseline reference data for future murine disease models.
This study establishes baseline mechanical properties and regional variations along the length of the normal mouse aorta, providing a reference for future cardiovascular disease models.
Guo et al. (2003) studied Normal mouse aorta mechanical properties (n=7). Stepwise pressure increases was evaluated on Mechanical properties (circumferential and longitudinal stress-strain relationships, transmural strain). In C57bl/6 mice, residual circumferential strain led to uniform transmural strain of the aorta at pressures of 60-120 mmHg, with 85% of volume compliance located in the thoracic aorta.
