Chaos in cell division – How chromosomal defects arise in cancer cells

When cells divide, the newly duplicated set of chromosomes is distributed evenly to the two newly forming daughter cells. This process is regulated by two polar bodies called centrosomes. Between the two centrosomes, protein fibers arise that appear like a spindle-shaped structure under the microscope. Along these fibers, one chromosome set each is pulled towards one of the poles. This normally ensures that each daughter cell is fully equipped. In cancer cells, however, scientists often observe higher or lower numbers of chromosomes than normal. This can be at…
