| Outline of Final Research Achievements |
We have been analyzing molecular interaction between tumor cells and lymphatic endothelium using lymphatic endothelial cell (LEC) line and gynecologic cancer cell line. After establishment of immortalization and cultivation of LEC, we observed elevated expression of cell adhesion molecules on LEC by adding inflammatory cytokine, TNFα. The lymphatic vessels are supposed to have a certain role in lymphatic metastasis by promoting cell adhesion. It was confirmed that a uterine cervical cancer cell, SKG-2 formed cell spheroid in a three-dimensional culture dish. It is suggested that this cell spheroid possesses the biological character mimicking the gynecologic tumor in cancer microenvironment.
