Guided by polarity complexes, spindle orientation and unequal segregation of determinants such as Numb and Prospero, this process maintains stem‑cell pools, drives tissue development and prevents uncontrolled proliferation. Its disruption contributes to degenerative disease and cancer.

Their precise regulation ensures accurate DNA duplication, faithful chromosome segregation, and controlled cell proliferation. Understanding these genes is essential for explaining genomic stability and the molecular basis of cancer.
