Detailed explanation-1: -Most cell types are polarized with distinct structural orientations or protein localization patterns that allow cells to perform specialized functions. Epithelial cell polarity is characterized by cells with apical and basolateral membrane domains separated by adherens and tight junctions.
Detailed explanation-2: -An epithelium has a free surface, the apical surface, exposed to the outside, and an attached surface, the basal surface, resting on the underlying connective tissue.
Detailed explanation-3: -Polarity is a fundamental property of epithelial cells. In this review, we discuss our current knowledge of the polarity of a stratified epithelium, the epidermis, focusing on similarities and differences with simple epithelial models.
