Association of centromeric heterochromatin with the nucleolus in mouse sertoli cells
The Anatomical Record, 1983AbstractIn adult Sertoli cells of most strains of mice, all the centromeric heterochromatin is condensed in two chromocenters, one on each side of a single, large nucleolus. In a random‐bred Swiss OF‐1 strain, however, the nucleus has a different structural organization. Part of the heterochromatin is seen as chromocenters in contact with the nucleolus;

Classification of Benign or Malignant Cell Nuclei using Nucleolus
2019 8th International Congress on Advanced Applied Informatics (IIAI-AAI), 2019Cytology directly examining cells in the early detection of cancer plays an important role in the medical diagnosis, but this diagnosis depends on the experience and technology of a pathologist. Problem is that it costs time for the examination and its objectivity is poor in the less experienced pathologist.

Visualization of the Nucleolus in Living Cells with Cell-Penetrating Fluorescent Peptides
2016The nucleolus is the hallmark of nuclear compartmentalization and has been shown to exert multiple roles in cellular metabolism besides its main function as the place of ribosomal RNA synthesis and assembly of ribosomes. The nucleolus plays also a major role in nuclear organization as the largest compartment within the nucleus.

Nucleolus-like bodies in micronuclei of cultured Xenopus cells
Experimental Cell Research, 1979Two of the 36 chromosomes in Xenopus laevis are known to carry nucleolar organizer loci. Partitioning of the chromosomes of cultured, early-passage Xenopus cells among variable numbers of micronuclei could be induced by extended colcemid treatment. A large, obvious nucleolus occurred in a maximum of 4 micronuclei per colcemid-induced tetraploid cell ...

Localisation of nucleolus-organising regions in interphase cells
Cell and Tissue Research, 1979A technique based on the use of silver solutions, which selectively stains the nucleolus-organising regions (NORs) in chromosomes, was applied to interphase Ehrlich tumour cells. The results indicate that nucleolar fibrillar centres correspond to the NORs.

Hybrid Contour Model for Segmentation of Cell Nucleolus and Membranes
2009 2nd International Conference on Biomedical Engineering and Informatics, 2009Regional difference is the kernel guidance in the area of image segmentation. In this paper, we present a novel region- based active contour model that could be applied to detect the contour of both nucleolus and cell membrane from the background. Both local and global intensity information are used as the driving forces of the active contour model on ...

A nucleolus-specific phosphoprotein in mouse ascites tumor cells
Molecular Biology Reports, 1976Analysis of proteins in nucleoli and chromatin of mouse ascites tumor cells labeled with [32P]orthophosphate by SDS-polyacrylamide gel electrophoresis showed that a highly radioactive protein was localized in the nucleoli. This protein was purified and the final preparation appeared as a single component on hydroxylapatite column chromatography with or

The development of the nucleolus of the ovarian nurse cell of Drosophila melanogaster
Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1970A description is given of the development of the nucleoli of the ovarian nurse cells of Drosophila melanogaster during stages 7 through 10 of oogenesis. This developmental period lasts about a day, and during it the volumes of the nurse cell nucleolus, nucleus and cytoplasm all double once every 4–5 hours.

Compartmentalization of the cell nucleus: case of the nucleolus
1993The nucleolus is the most prominent nuclear organelle. Only one major function is ascribed to the nucleolus: here ribosomal RNA (rRNA) is transcribed, processed and assembled into preribosomal particles (Reeder, 1990 Warner,1990). The growing eukaryotic cell contains thousands of different transcripts, but the nucleolar rRNA synthesis accounts for ...
