Staining of the spindle apparatus in human lymphocyte and fibroblast cultures

Human Genetics, 1976
The spindle apparatus of human mitoses can be preferentially stained with Giemsa if the cells are fixed with methanol--acetic acid and treated for about 15 min with 0.1 X SSC at 92 degrees C and for 18 h with 2 X SSC at 60 degrees C.

Reactivation of isolated mitotic apparatus: Metaphase versus anaphase spindles

Cell Motility, 1991
AbstractMitotic spindles isolated from sea urchin eggs can be reactivated to undergo mitotic processes in vitro. Spindles incubated in reactivation media containing sea urchin tubulin and nucleotides undergo pole‐pole elongation similar to that observed in living cells during anaphase‐B.

Spindle Birefringence of Isolated Mitotic Apparatus Analysed by Pressure Treatment

Journal of Cell Science, 1976
ABSTRACT Sea-urchin zygote mitotic apparatus (MA) isolated in a glycerol/dimethylsulphoxide medium were treated with pressure. Pressure treatment had no effect on spindle birefringence when MA were in full-strength isolation medium. After placing MA in quarter-strength isolation medium, pressures of 4·0 × 103– 1·8 × 104 Ibf in.−2 (2·76 ×

Arrangement of spindle apparatus in mitoses of different ploidy

Experimental Cell Research, 1975
Abstract In non-hypotonically treated mitoses from tissue cultures of Microtus agrestis , both the constitutive heterochromatin of the sex chromosomes and the spindle apparatus were stained by the Giemsa C-banding technique. By means of counting the heterochromatic chromosomes, we determined the cell ploidy and studied the number of centrioles and ...

Cytokinesis: relative alignment of the cell division apparatus and the mitotic spindle

Current Opinion in Cell Biology, 2003
The cell division apparatus is assembled at different stages of the cell cycle in different eukaryotic organisms. Mechanisms exist in all organisms, however, to ensure that the cell division apparatus and the mitotic spindle are aligned perpendicular to each other.

The evolutionary significance of ultrastructural variations in the micronuclear spindle apparatus in the genus Paramecium

Biosystems, 1975
Ultrastructural variations of micronuclear mitosis in three species of Paramecium have been reviewed for the purpose of hypothesizing possible evolutionary relationships. P. bursaria is considered to be the most primitive species because it has complex kinetochore-equivalents termed microlamellae which attach to microfilaments. P.

Modelling the mitotic apparatus

Acta Biotheoretica, 1995
This bibliographical review of the modelling of the mitotic apparatus covers a period of one hundred and twenty years, from the discovery of the bipolar mitotic spindle up to the present day. Without attempting to be fully comprehensive, it will describe the evolution of the main ideas that have left their mark on a century of experimental and ...
