Outline of Final Research Achievements |
Liver is known as frequently hematogenous metastatic organ. To perform a detailed analysis of liver immune cells, colon cancer cell line Colon26 was transplanted subcutaneously into Balb/c mice. As a result of this transplantation, Ly6G positive neutophil migration was observed prior to liver metastasis of cancer cells. A quantitative RT-PCR experiment shows that significant over expression of chemokine KC in the liver. Liver metastasis was reduced by subcutaneous cancer transplant by using via spleen metastasis model. Immuno-depletion of neutrophil significantly enhances liver metastasis by using via spleen metastasis model. These results indicate that neutrophil plays inhibitory role on colon cancer liver metastasis.
