Cell polarity

Epithelial cells demonstrate structural and functional polarity, with: An apical domain, which may bear cilia, microvilli, or stereocilia. This domain is the interface with the external environment. A basolateral domain, which contains junctional complexes and cell adhesion molecules. This domain is the interface with the internal environment.
