From: Multiaxial Lenticular Stress-Strain Relationship of Native Myocardium is Preserved by Infarct-Induced Natural Heart Regeneration in Neonatal Mice

Figure 5

Average Stress-Strain Curves. Average stress-strain relationship of left ventricular tissue from mice after sham or myocardial infarction (MI) surgery on postnatal day 1 (P1) or postnatal day 7 (P7), derived from lenticular hydrostatic deformation testing. (a) After P1 surgery, sham (n = 22) and MI hearts (n = 22) exhibited similar stress-strain curves. (b) After P7 surgery, MI hearts (n = 20) exhibited significantly stiffer behavior than sham hearts (n = 20). Shaded region represents standard error.
