Here we report that β-catenin participates in a third cellular process, the establishment of a bipolar mitotic spindle. During mitosis, β-catenin relocalizes to mitotic

Mitotic spindle assembly and regulation. Cell division is essential to the propagation of life. During cell division, mitotic spindles segregate duplicated

Spindle orientation in turn controls the placement of daughter cells within a tissue, influencing tissue morphology. Recent findings implicating tumor suppressor proteins in spindle orientation bring Spindle fibres constitute mitotic and meiotic spindle during cell division. They are formed by microtubules and play an important role during nuclear division.
