The mitotic spindle consists of dynamic microtubules and many associated factors that form an antiparallel, bipolar array. Duplicated chromosomes are attached to microtubules of the spindle and then are physically separated by the spindle to opposite ends of the dividing cell. Spindles vary in their morphology and assembly pathway depending on the cell type and organism, but common underlying mechanisms derive from the dynamics of the microtubules and microtubule-based motor proteins, and the activities of chromosomes themselves. In this chapter, we describe the multiple mechanisms that promote assembly of the dynamic mitotic spindle.
