At the onset of division, the cell forms a spindle, a molecular machine responsible for equal distribution of chromosomes between the daughter cells. It is a highly complex structure made of microtubules and associated proteins. During prometaphase, kinetochore microtubules extend from poles on either end of the cell and attach to the kinetochores, multiprotein structures on the centromeres of the chromosomes. In this thesis, fluorescence microscopy was used for live-cell imaging of human cells. U2OS (CENP-A-GFP, mCherry-α- tubulin) cells were visualized and analyzed. It was shown that the spindle length decreases and the width increases during the prometaphase. Despite the changes in spindle length and width, the contour of this cell structure remains unchanged.
