title: [Number and mass of the myocytes of the mouse heart].
abstract: The mean number of cardiomyocytes is constant in the heart ventricles of 1, 1.5-2, 3-4, 5-6 and 12-month old mice. However, differences in the myocyte number among mice of the same age and with similar heart weight may reach 30%. There are only small differences in the mean ploidy among these mice. The mean protein content in the myocytes correlates to the ventricle weight. In some mice, however, no correlation was observed between the myocyte and ventricle weights, or between the calculated dry and wet weights of myocytes.
