Outline of Final Research Achievements

Tumor lymphagiogenesis is promoted by stepwise process although it has not been fully elucidated. Among tumor microenvironment, tumor-associated angiogenesis has been well characterized. Furthermore, it is well understood that vascular system plays a key role in drug delivery during chemotherapy. Therefore, in the present study, we aimed to show a significant role of lymphatic vessels in drug delivery as well as clearance during the therapy. Lymphatic vessels show persistent enlargement during inflammation, leading to reduced draining function. Furthermore, tumor-associated lymphatic vessels are known to show the reduction of flow in tumor progression. Here we subjected transgenic mice which express green fluorescent protein under the Prox1 promoter which is specifically activated in lymphatic endothelial cells, and successfully found that fluorescence-labeled dextran was absorbed by the lymphatic capillary vessels.
