Human HeLa cancer cells, anaphase

A deconvolved wide-field fluorescence microscope image of human HeLa cancer cells in anaphase of mitosis. The chromosomes are stained green with DAPI. The microtubules of the cytoskeleton/spindle are purple. The red is Aurora B, a protein kinase involved in the polymerisation/depolymerisation of the microtubules during mitosis. Yellow is the overlap between the red and green fluorescence.
