title: [Structure of the centriolar complex in the hepatocytes of intact and regenerating mouse live].
abstract: The structure of the cellular center in polyploid hepatocytes of intact and regenerating liver of adult mice has been studied. It was shown that the structure of the centriolar complex depends on stages of the cellular cycle. No pericentriolar structures (such as satellites, appendages and others) and cytoplasmic microtubules were found in the centriolar complex within G0-period. The satellites and appendages are formed in the half of the centrioles within G1-period. The microtubules can branch off some satellites; the daughter centrioles begin to form within S-period; there are diplosomes in the cells within G2-period, some mother centrioles are surrounded with the fine fibrillar halo. It is concluded that the structure of the centriolar complex within G0-period is distinguished by that within G1-period. The structure of the centriolar complex in polyploid hepatocytes has the same feature of reorganization in certain interphase periods of the cell cycle as in diploid cells of some cultured cells and the thyroid epithelium.
