Cardiomyocytes, also known as myocardial fibers, are the muscle cells which form the heart tissue. Previous studies have indicated that fetal mammalian cardiomyocytes maintain the regeneration capacity, which promotes the fetal heart growth. Regardless of environment insults including nutrient deprivation, changes of blood flow, along with mechanical and volume loading [1], embryonic mammalian cardiac muscle cells are also related to robust proliferation response. Similarly, the hearts of 1-day-old neonatal mice could also be fully regenerated after surgical resection of the left ventricular a...
