The dental lamina connects the developing tooth bud to the epithelial layer of the mouth for a significant time.

Tendon cells form a connecting epithelial layer between the muscle and shell in molluscs.

Other nerve and muscle cells lie just under the epithelial layers.

Loss the normal organization of the epithelial layers.

The distinction between the epithelial layers may be lost.

If the epithelial layer gets dry or irritated, it may cease to function.

Cloudiness seems to be confined to the epithelial layer and probably susceptible of considerable improvement.

Surface ablation methods differ only in the way the epithelial layer is handled.

The original cuboidal epithelial layer may be also severely impaired or missing.

Generally, this shape change is coordinated across many cells of an epithelial layer, generating forces that can bend or fold the cell sheet.
