| Outline of Final Research Achievements |
We have reported that tumor endothelial cells are heterogeneous depending on tumor malignancy. In this study, we tried to evaluate the difference of tumor endothelial cells of hepatocellular carcinoma, in order to develop novel molecular for targeting liver cancer. We identified a marker that is highly expressed in poorly differentiated cancer compared to well-differentiated cancer and show that this molecule plays an important role for tumor cell metastasis. These results suggested that tumor endothelial cell may be involved in tumor metastasis in malignant hepatocellular carcinoma.
