Cross-sectional structure of the central mitotic spindle of Diatoma vulgare. Evidence for specific interactions between antiparallel microtubules
During the transition from prometaphase to metaphase, the cross-sectional area of the central spindle of Diatoma decreases by a factor of nearly two, both at the poles and at the region of overlapping microtubules (MTs) near the spindle equator. The density of spindle MT packing stays approximately constant throughout mitosis. Optical diffraction analysis of electron micrographs shows that the ...

متن کاملThree-dimensional structure of the central mitotic spindle of Diatoma vulgare
Central mitotic spindles in Diatoma vulgare have been investigated using serial sections and electron microscopy. Spindles at both early stages (before metaphase) and later stages of mitosis (metaphase to telophase) have been analyzed. We have used computer graphics technology to facilitate the analysis and to produce stereo images of the central spindle reconstructed in three dimensions. We fi...
متن کاملOn the mechanism of anaphase spindle elongation in Diatoma vulgare
Central spindles from five dividing cells (one metaphase, three anaphase, and one telophase) of Diatoma vulgare were reconstructed from serial sections. Each spindle is made up of two half-spindles that are composed almost entirely of polar microtubules. A small percentage of continuous microtubules and free microtubules were present in every stage except telophase. The half-spindles interdigit...
