Light microscopic identification of lymphatic vessels of the human small intestine was studied immuno-histochemically with a monoclonal antibody specific for human thoracic duct (mAb-D) and rabbit anti-human laminin antibody (anti-L). Two types of vessels were observed with anti-L; one strongly reacted with regularly outlined vessels and the other weakly reacted with irregularly outlined vessels and thin walls. Immunoreactivity to mAb-D was strong in the weakly reacting vessels, and the strongly reacting vessels did not react to mAb-D. Immunoreactivity of lymphatic vessels to anti-L has been reported to be weaker than that of the blood vessels; only irregularly outlined vessels which were weakly immunostained with anti-L reacted to mAb-D and no cross-reaction to mAb-D was observed in the regularly outlined vessels. This indicates that the vessels strongly reacting with anti-L are blood vessels and the vessels immunostained with mAb-D must be lymphatics. The study shows that it is possible to identify lymphatic vessels light microscopically by mAb-D. This method will be useful in studying the fine distribution of lymphatic vessels in normal tissue and also in pathological tissue such as metastasis of malignant tumors.
