  • Title: Rotation of the cell nucleus in living cells: a quantitative analysis.
    Author: Bard F, Bourgeois CA, Costagliola D, Bouteille M.
    Journal: Biol Cell; 1985; 54(2):135-42. PubMed ID: 2933103.
    Abstract:
    Nuclear rotation is observed in a variety of cell types. However, few quantitative analyses are reported and the significance of this phenomenon is still unclear. To investigate this type of nuclear movement, we performed a quantitative analysis in mouse L-929 fibroblasts, a cell line chosen since it displays a high nuclear rotational activity. Analyses were performed using time-lapse microcinematography. The relationship between nuclear rotation and other cellular phenomena such as the cell cycle and locomotion were studied. Then, we investigated the rotation in a population of sister cells to study whether it is genetically determined. Finally, we performed a qualitative analysis of nuclear rotation in different cultured cell lines. Results show that nuclear rotations preferentially occur during the phases of the cell cycle which surround mitosis.
