[more ▼] 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).

[more ▼] Recent electron microscopic immunolocalization studies (Scheer and Rose, 1984) indicated that RNA polymerase I is located in, and probably confined to, the fibrillar centres of the nucleoli. This conclusion appears to be in contradiction to previous autoradiographic studies reporting that transcription of rRNA genes takes place in the dense fibrillar component. Despite the fact that rRNA transcription occurs in the dense fibrillar component of Ehrlich tumour cell nucleoli, we show in the present paper that dense fibrillar component containing rapidly labelled RNA can be visualized not only around but also inside the fibrillar centres.
