Evaluation and therapeutic application of lymphangiogenesis using animal model with lymph node metastasis of lung neoplasm

We have explored seeds that played the role of lymphangiogenetic inhibitor and evaluated 80 series of agents in the library. As a result, Shikonin had a strong inhibitory effect to lymphangiogenesis, and this affection was introduced by increasing of adhesion to some extracellular matrix, and is not by migration of lymphatic endocell. On the other hand, Deoxyshikonin which is a derivative from Shikonin, made an opposite reaction to increase an angiogenesis of lymphatic vessels.
