[Mitotic activity of the myocardium in early ontogenesis of rabbits after minor mechanical injury to the heart].
The data are provided on proliferative activity of myocytes in rabbit embryos and neonates. In rabbit embryos, in which myocardial regeneration is effected at the cellular level, mitoses of myocytes are largely important for myocyte proliferation. In rabbit neonates which do not show any complete regeneration of the myocardium, mitoses of myocytes are of primary importance for myocardial polyploidy. Minor mechanical injury to rabbit myocardium in early ontogenesis contributes to activation of the processes of hear muscle differentiation.
