A deconvolved wide-field fluorescence microscope image of human HeLa cancer cells in anaphase of mitosis. The chromosomes are green (DAPI stain). The microtubuules of the cytoskeleton/spindle are pink/mauve. The red is Aurora B, a protein kinase involved in the polymerisation/depolymerisation of microtubules during mitosis, and also associated with the centromeres, which show up as blackish blobs.
