A cell cycle process that sets the alignment of mitotic spindle relative to other cellular structures.

Any process that activates or increases the duration or quality of sleep, a readily reversible state of reduced awareness and metabolic activity that occurs periodically in many animals.

The process resulting in the physical partitioning and separation of a neuroblast into two daughter cells with different developmental potentials.

Any process that modulates the rate, frequency or extent of the establishment of bipolar cell polarity. Bipolar organization is the organization that is a mirror image along an axis from a plane.

Division of a stem cell during which it retains its identity and buds off a daughter cell with a new identity.

A structure comprised of a core structure (in most organisms, a pair of centrioles) and peripheral material from which a microtubule-based structure, such as a spindle apparatus, is organized. Centrosomes occur close to the nucleus during interphase in many eukaryotic cells, though in animal cells it changes continually during the cell-division cycle.

The array of microtubules and associated molecules that forms between opposite poles of a eukaryotic cell during mitosis or meiosis and serves to move the duplicated chromosomes apart.
