The aim of the present work was to study the distribution and the behaviour of the silver-staining nucleolar organizer region (Ag-NOR) proteins at the ultrastructural level during interphase and mitosis in five human and murine cancerous cell lines each characterized by a typical nucleolar morphology. During interphase the Ag-NOR proteins are restricted to the fibrillar centres (F.C.) and/or to the dense fibrillar component (D.F.C.). During prophase the silver-staining components come into close contact with some chromosomes and are arranged with a typical polarity: chromosome, F.C. and D.F.C. Then F.C. and D.F.C. together form roundish silver-stained structures and integrate in part within indentations at the periphery of the metaphase chromosomes. During anaphase and telophase large and small spherical silver-staining structures may be seen. They correspond respectively to the metaphase NORs and to numerous structures which appear de novo within ribonucleoprotein (RNP) material localized between the chromosomes. During late telophase the number of the small silver-staining structures decreases whereas the size of the larger ones increases. Then the interphase nucleoli recover their typical shape. These results suggest that when rRNA synthesis is impaired during mitosis the inactive NORs assume a structure and a localization which are not typical of the cell line. In contrast the F.C. and D.F.C. are probably two aspects of the NORs whose typical distribution, relative to the other nucleolar components, gives the interphasic nucleolus its characteristic morphology.

In the present study, we analysed the relationships between various nucleolar components in Ehrlich tumour and HEp-2 cells, using acetylation. Under these conditions, we found contacts between the condensed intranucleolar chromatin and the fibrillar centre, illustrating the continuity between the DNA present inside the fibrillar centre and that of condensed associated chromatin. We also found that although the dense fibrillar component is usually situated at the periphery of the fibrillar centre, it is sometimes found inside the centre. On the other hand, the layer of dense fibrils bordering the fibrillar centre is interrupted by nucleolar interstices. In addition, in HEp-2 cell nucleoli with a reticulated appearance, the numerous small fibrillar centres are bound together by strands of dense fibrillar component. These observations are discussed in terms of relationships between nucleolar ultrastructure and function(s). [less ▲]
