Outline of Final Research Achievements |
A novel cancer research model of transgenic zebrafishes, which allowed a precise analysis of cancer cell dynamism for metastasis through blood and lymphatic vasculature, was developed. Live imaging of human tumor cells in the metastasis model unveiled some unique patterns of tumor vascular invasion and of motion of tumor cells through vasculature. The zebrafish implanted with human pancreatic cancer cells producing VEGF-A often demonstrated focal growth of vascular endothelial cells at tumor invasion sites. The molecular mechanisms involved in tumor vascular invasion including microangiogenesis and/or lymphangiogenesis is under investigation. 達成度
