title: Cellular growth of cardiac muscle after birth.
abstract: Present concepts concerning DNA synthesis in the heart have been reviewed, and a speculative theory presented involving control of DNA synthesis in the developing heart. Research describing DNA synthesis in myocytes of the weanling rat heart undergoing hypertrophy has been presented. Its possible use for testing the control theory is suggested.
