Epithelial cell polarity from the outside looking in.
Epithelial cell polarity may be regulated by protein sorting in the Golgi and delivery to different membrane domains, a view from the inside looking out. But from the outside looking in, cell adhesion may be required first to establish sites for delivery, retention, and separation of membrane proteins, and delivery of presorted proteins from the Golgi subsequently reinforces and maintains different membrane domains.
