The proliferative activity of myocardial capillary wall cells in variously aged swimming-exercised rats
Acta Pathologica Et Microbiologica Scandinavica. Section A, Pathology
|January 1, 1979
Abstract:
Cellular proliferation was studied by incorporation of 3H-thymidine in the hearts of young, adult and old swimming-exercised rats. The proliferative activity was measured by scintillation counting. The swimming exercise induced a significant proliferation of capillary wall cells in the younger age groups, suggesting a neoformation of myocardial capillaries in these rats, whereas no cell proliferation was recorded in the old rats.
