EPITHELIUM3D

Firstly, epithelial cells are carefully placed side to side through specific cell-to-cell adhesion molecules. These molecules form specialised cell junctions. Epithelium creates a selective barrier between the external environment and the underlying connective tissue. It facilitates or inhibits the passage of specific substances between the exterior environment and the underlying connective tissue compartment. The different domains of the epithelial cell and their names (basal, apical and lateral) are illustrated in the image on the right.
