Abstract
An experimental [rat] model for the study of the control of tissue growth by cell proliferation (hyperplasia) and cell enlargement (hypertrophy) is proposed. The model is constructed on the basis of the fact that, when DNA replication and cell proliferation cease in cardiac muscle during neonatal development, subsequent growth of the ventricular tissue is due to cell enlargement. The time period during development when this change in growth pattern occurs is documented with the cessation of DNA replication and the synthesis and accumulation of myosin as biochemical parameters. Adrenergic innervation of the heart may be the physiological signal that changes the growth pattern of the muscle from hyperplasia to hypertrophy.This publication has 9 references indexed in Scilit:
