cardiovascular system
• the number of cardiomyocytes is increased
• however, cardiac tissue morphology, heart-to-body weight ratio, and heart function are normal under physiological conditions and no cardiac hypertrophy is seen
|
• hearts show increased cardiomyocyte proliferation
|
• mice subjected to myocardial infraction induced by coronary artery ligation exhibit reduced scar size, improved left ventricle function, and increased cardiomyocyte proliferation, indicating improved myocardial repair and cardiac function after ischemic injury
