Science, 1989
Data that describe both the structure and the physiology of the mitotic spindle are reviewed. Some of the molecules that have been shown to play a role in mitosis are tabulated, and how mitosis might work is considered.

AbstractWithin the last decade, the study of mitosis has evolved into a multidisciplinary science in which findings from fields as diverse as chromosome biology and cytoskeletal architecture have converged to present a more cohesive understanding of the complex events that occur when cells divide.

A precise coordination of multiple cell cycle events is required to ensure proper mitosis. Chromosome cohesion must be maintained until all chromosomes are attached to opposite poles of the mitotic spindle and aligned at the metaphase plate. At the onset of anaphase, the activity of separins contributes to the release of cohesins from chromosomes ...

THE metamyelocyte of bone marrow is usually classified with the more mature forms of granulocyte1 and is considered to be in the maturation fraction2,3 rather than in the proliferative group of bone marrow cells. There are numerous reports that the metamyelocyte is unable to divide, and that mitosis is confined to less-differentiated forms of ...

Calcium is thought to be involved in regulating mitotic transitions. The basis for this view is set out. Recent data from experiments on sea urchin embryos is discussed. The relative simplicity of the embryonic cell cycle and the relative ease with which cell physiology can be done in sea urchin embryos has allowed the clear demonstration that the ...

Publisher Summary This chapter discusses the ultrastructure of vegetative nuclear division, that is, mitosis in fungi and closely related groups. Mitotic divisions occurring in the vegetative phase of the fungi are essentially the same as in higher organisms, although the details are frequently obscured by the small size of the nuclei.

IN the ascus of Neurospora, meiosis and mitosis appear to resemble those in higher plants1–4. However, within the mycelium of Neurospora and of a number of other fungi, some observers report that the conventional stages of nuclear division are lacking, that the spindle is absent, and that the nuclei divide by becoming constricted and pulling in two5–8.

Mitosis controls the Golgi and the Golgi controls mitosis
Current Opinion in Cell Biology, 2007In mammals, the Golgi complex is structured in the form of a continuous membranous system composed of up to 100 stacks connected by tubular bridges, the 'Golgi ribbon'. During mitosis, the Golgi undergoes extensive fragmentation through a multistage process that allows its correct partitioning and inheritance by daughter cells.

Although normal mitosis is characterized by the regular alternation of chromosome reproduction and segregation of daughter chromosomes, the two processes are not necessarily correlated, and their relationship can be changed in different ways (cf. Oksala, 1954).

The mitotic spindle is a fascinating protein machine that uses bipolar arrays of dynamic microtubules and many mitotic motors to coordinate the accurate segregation of sister chromatids. Here we discuss recent mathematical models and computer simulations that, in concert with experimental studies, help explain the molecular mechanisms by which the ...
