| Research Abstract |
The aim of this study was to clarify the mechanism of liver metastasis after liver transplantation. Splenic injection model was used as micrometastasis setting via portal vein. Macroscopic metastasis was observed in all mice, but IFN administration significantly decreased number of liver metastasis (19.3 versus 6.0, p<0.05). Microvessel density was quantified using CD34 immunostaining and IFN significantly suppressed angiogenesis compared with control. Expression of adhesion molecules such as VCAM and ICAM did not correlate with IFN treatment.
