Protection of organ geometry and histology. Exaggerated cardiomegaly (A and B), fibrosis (C through F), and myocardial disarray (G through I) in response to [TAC-iPS(-)] was blunted by stem cell therapy [TAC-iPS(+)]. *P<0.05 vs. TAC(−); †P<0.05 vs. TAC-iPS(−). Bar represents 2 mm in (A). Ao indicates aorta; CI, confidence interval; DAPI, 4′,6′-diamidino-2-phenylindole; iPS, induced pluripotent stem; LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle; TAC, transverse aortic constriction; white arrow, LV free wall; yellow arrow, LV dimension; α-actinin, sarcomeric α-actinin.
