Daily administration of exogenous cAMP to neonatal rat liver primary cultures caused a decrease of the total cellular volume, membrane space and SER coupled with a marked increase in the complement of RER, free ribosomes and polysomes and in the volume of nuclei after 3 days in hepatocytes; moreover the Golgi apparatus appeared to have undergone hypertrophy and the microtubules to have formed noticeable bundles. The present results support the view that the functioning of the RNA and protein synthesizing machinery of neonatal rat hepatocytes is stimulated by exogenous cAMP.

Abstract
Daily administration of exogenous cAMP to neonatal rat liver primary cultures caused a decrease of the total cellular volume, membrane space and SER coupled with a marked increase in the complement of RER, free ribosomes and polysomes and in the volume of nuclei after 3 days in hepatocytes; moreover the Golgi apparatus appeared to have undergone hypertrophy and the microtubules to have formed noticeable bundles. The present results support the view that the functioning of the RNA and protein synthesizing machinery of neonatal rat hepatocytes is stimulated by exogenous cAMP.
