Outline of Final Research Achievements

It is reported the formation of supportive metastatic microenvironment, referred to as premetastatic niche, before arrival of metastatic cells. Tumor endothelial cells, lining tumor blood vessels, is known to circulate in blood. In this study, we investigated the role of TECs in tumor metastasis. TECs adhered lung tissues more compared to normal endothelial cells when they were injected into mice intravenously. We established skin transplantation model using GFP mouse. Tumor cells were injected under the skin graft, and then we detected GFP positive cells in the blood of the mouse. We will examine the mechanisms of tumor metastasis by circulating TECs which secrete many cytokines.
