Abstract (original English)
Background and aim Cell-based transplantation therapy using hepatocytes, hepatic stem cells, hepatocyte-like cells induced from stem cells, etc. is thought to be an attractive alternative to liver transplantation, and have been studied to date. For its clinical application, however, it is extremely important to develop a model that reproduces the pathological conditions with indication for treatment and enables the study for the ideal treatment strategy. Methods The transgenic mice which express the thymidine kinase (TK) gene of human herpes simplex virus (HSV) in their hepatocytes with normal immunity has been developed (designated as HSVtk). After ganciclovir (GCV) administration which injure TK-expressing hepatocytes, the primary hepatocytes (PHs) isolated from green fluorescent protein (GFP) transgenic mouse (GFP-tg) were transplanted to HSVtk intrasplenically, and replacement index (RI) with transplanted PHs in the liver, liver histology, and mRNA expressions in the liver were analyzed up to 8 weeks after transplantation. Results HSVtk without PH transplantation after GCV administration developed persistent liver failure with degenerated hepatocytes, persistent elevation of ALT and hepatic p16 mRNA levels, suggesting the existence of cellular senescence in the base of the disease. When autologous GFP-PHs were transplanted to HSVtk, the transplanted cells were successfully
