| Research Abstract |
We analyzed the adhesion formation after hepatectomy in mice and humans. After hepatectomy, NKT cells in the liver accumulated nearby cut end and produced IFN-γ. Hepatocyte produced PAI-1, fibrinolysis factor, dependent on IFN-γproduction. These molecules are crucial role for adhesion formation after hepatectomy. Mice treated with recombinant HGF was decreased adhesion formation after hepatectomy though inhibition both IFN-γand PAI-1 production. This treatment may apply for the adhesions in human cases in near future.
