Summary An immunohistochemical study of rat fetal hearts at 20 days of gestation revealed the presence of immunoreactive atrial natriuretic factor (ANF) in cardiocytes of the left and right atria as well as in certain cells is the left and right ventricles. In the atria, cells of the adluminal pectinate muscles appear more densely labeled than the more peripheral mural cells. In the ventricles, immunoreactive cells were found only in adluminal cardiocytes of the presumptive trabeculae and papillary muscles. The results indicate that ANF is synthesized in the perinatal heart, and that the presence of this hormone in the ventricular cardiocytes may be of only temporary nature during certain stages of pre- and postnatal development.
