Regeneration of lymphatic vessels in the ear of the guinea pig.

The regenerative capacity of injured lymphatic trunks was compared to that of lymphatic capillaries following physical and chemical injuries using the techniques of micro-injection. Some transected lymphatic trunks regenerate whereas lymphatic trunks having 2 mm segments excised did not regenerate. Flow of lymph was diverted to collateral vessels. In contrast to lymphatic trunks, lymphatic capillaries showed remarkable regenerative capacity following both physical and chemical injuries.
