Contribution of subcutaneous connective tissues to the epithelialization and cyst formation by the skin transplanted subcutaneously.

Skins and hollow organs have been shown to form epithelialized cysts when transplanted into subcutaneous tissue of a recipient animal, expanding their surface areas. This system seems to offer a good potential for regenerating organs. We investigated the functional and structural contribution of epithelia and connective tissue compartments in this regeneration system with two experimental systems.
