[Glycogen content in the DNA-synthesizing and nonsynthesizing hepatocytes of rats of different ages]

The glycogen content in DNA synthesizing and non-synthesizing hepatocytes has been conducted cytochemically during the rat postnatal development. Within all the periods of investigation, the average glycogen content in DNA synthesizing hepatocytes (phase S) are shown to be lower than that in hepatocytes being in phases G0 and G1. The absolute value of reduction of the glycogen content with diploid mononucleate hepatocytes in S-phase is almost the same for rats of all the age groups examined. The absolute value of reduction of the glycogen content in diploid binucleate hapatocytes in S-phase is twice as much as that in diploid mononucleate hepatocytes being at the same stage of the cell cycle. Regardless of the postnatal development stage and of the total glycogen content in the liver, the glycogen content in DNA non-synthesizing hepatocytes of different ploidy is in conformity with the genome number.
