| Outline of Final Research Achievements |
Focusing on scaffold function of fibrin, we carried out research for development of immunotherapy for solid tumors. The microstructure of fibrin was observed with electron microscope to determine the optimal dilution. In macrophage infiltration assay using fibrin containing OK-432, significantly large number of cells were observed in fibrin gel compared to fibrin without OK-432. In the rat portal vein embolization model, we evaluated the extent of liver tissue damage and cell infiltration due to the difference of embolic materials. When embolization was performed using embolic material containing fibrinogen, histological damage of the liver in association with significant number of infiltrating macrophages was observed until 7 days after the embolization. These data together suggested that coexistence of fibrin and OK-432 has affected the local immune environment.
