Theory of Mitotic Spindle Oscillations
Physical Review Letters, 2005During unequal cell division the mitotic spindle is positioned away from the center of the cell before cell cleavage. In many biological systems this repositioning is accompanied by oscillatory movements of the spindle. We present a theoretical description for mitotic spindle oscillations.

The mitotic spindle, due to its striking form, has been imaged for well over 100 years. Composed largely of microtubules and chromosomes, the spindle also contains numerous proteins whose roles include biochemical and biophysical regulation of mitosis.

I PREVIOUSLY suggested that the shape of the metaphase spindle cannot be maintained if there is tension in the component microtubules1. Spindle tension has been detected2,3 and could be due to some other component pulling the chromosomes over the rigid microtubular framework.

Mitotic Spindle Assembly In Vitro
Current Protocols in Cell Biology, 2001AbstractThe protocols in this unit describe the preparation of materials for an in vitro assay of mitotic spindle assembly in Xenopus egg extracts. Fluorochrome‐labeled tubulin is used to visualize microtubule asters and spindles.

Control of Mitotic Spindle Length
Annual Review of Cell and Developmental Biology, 2010The mitotic spindle accurately segregates genetic instructions by moving chromosomes to spindle poles (anaphase A) and separating the poles (anaphase B) so that, in general, the chromosomes and poles are positioned near the centers of the nascent daughter cell products of each cell division.

Publisher Summary This chapter focuses on one aspect of the biochemistry of mitotic spindles—the presence of adenosine triphosphate (ATP) hydrolyzing enzymes. ATPase in the mitotic spindle is discussed. There is a physiological evidence for dynein ATPase in mitotic spindles.

GENETIC ANALYSIS OF THE MITOTIC SPINDLE
Annual Review of Genetics, 1996▪ Abstract Much of our understanding of the molecular basis of mitotic spindle function has been achieved within the past decade. Studies utilizing genetically tractable organisms have made important contributions to this field and these studies form the basis of this review.

Biochemistry of the Mitotic Spindle
1979Publisher Summary The mitotic spindle consists of the chromatic and the achromatic figure. The chromatic figure consists of the chromosomes and includes their attachment points to the spindle, the kinetochores. The achromatic figure is more difficult to define.

The Evolution of the Mitotic Spindle
1976Publisher Summary This chapter discusses the evolution of the mitotic spindle. The recounting of the evolutionary past of the mitotic processes of chromosome movement would entail tracing a gradual shift from membranes to micros as the primary producer of forces for chromosome movement.

Mescaline as a mitotic spindle inhibitor
Nature, 1976COLCHICINE and its methyl derivative colcemid not only inhibit microtubule self-assembly1 but also affect fast transport in nerve2. A report that mescaline likewise inhibits the rapid component of axoplasmic transport in nerve3, led us to investigate the effects of this drug on mitosis, and on purified microtubule protein (tubulin4).
