The attraction-sphere and centrosome lie in the cytoplasma in the neighbourhood of the nucleus.
Karyokinetic figure, the one centrosome much larger than the other.
At each pole of this spindle figure there often occur fibres radiating in all directions into the cytoplasm, and sometimes a minute granular body, the centrosome, is also found there.
Where pigment was present within the cells (sarcoma), the attraction-spheres were represented by quite clear unpigmented areas, sometimes with a centrosome in their midst.
Belajeff regards it as a true centrosome; but this is doubtful, for while in some cases it appears to be connected with the division of the cell, in others it is independent of it.
Its proximal centrosome (its distal one vanishing as such).
Centrosome.The centrosome is a minute homogeneous granule found in the cytoplasm of some cells in the neighborhood of the nucleus.
t.chr, Trophonuclear chromo- t.c, Trophonuclear centrosome.
k.c, Kinetonuclear centrosome.
And that idea is reinforced by the fact that three of the known MCPH proteins are found in the centrosome during cell division.
centrosome function in cell division, and tissue organization.
centrosome maturation would be expected to restore normal growth control.
During cell division, the duplicated centrosome helps to organize the mitotic spindle.
The centrosome or centrosphere is usually regarded as the dynamic centre of the cell and a special organ of division; but its absence in many groups of plants does not lend support to this view so far as plant-cells are concerned.
