Mitosis depends upon the action of the mitotic spindle, a subcellular machine that uses microtubules (MTs) and motors to assemble itself and to coordinate chromosome segregation. Recent work illuminates how the motor-driven poleward sliding of MTs — nucleated at centrosomes, chromosomes and on pre-existing MTs — contributes to spindle assembly and length control.
