(A) Regional principal stretches ?1, ?2 at end-diastole (ED) and end-systole (ES) during a cardiac cycle at the outflow (OT), equatorial (EQ), and apex (AP) regions of developing zebrafish heart at 3-, 4-, and 5-dpf where ?2 denote principal stretches near the latitudinal direction and ?1 denote that at the direction perpendicular from the former. From 4-, 5-dpf groups, at ED, we noted greater deformation (designated as ?2) at the direction near the ALR in each of OT, EQ, and AP regions. Same were found at ES state indicating their anisotropic deformation, except in AP from 4-dpf. From 3-dpf group, we noted only slightly anisotropic with significantly higher ?2 at AP region. Statistically significant differences (P < 0.05) are denoted by asterisk. (B) Ratios of principal stretch components (?2/?1) at ED and ES states from outflow (OT), equatorial (EQ), and apex (AP) regions. Statistically significant differences (P < 0.05) are denoted by asterisk |
