Mitotic spindle orientation in epithelial homeostasis and plasticity

Abstract excerpt

Polarized epithelia are a foundation of organ and appendage structures throughout Metazoa and serve as a physical barrier to preserve physiological functions. In proliferating epithelia, planar cell division occurs by orienting the mitotic spindle within the plane of the epithelium to ensure tissue organization. Conversely, loss of tissue architecture is a hallmark of carcinoma, and aberrant spindle orientation...
