PG - S174-8 AB - In this study, we investigated whether establishment of chimerism in donor liver with recipient-type bone marrow cells (BMCs) prior to liver transplantation could prolong the liver allograft survival. Donor female ACI rats were inoculated with recipient-type BMCs of male LEW rats via the portal vein, with or without irradiation as cytoablation, followed by intramuscular administration of FK506 for 5 days. At 1-2 months later, livers were harvested and transplanted into naive female LEW rats. No immunosuppressants were used. Chimerism in donor rats was confirmed by primers specific for the sex determinant Y chromosome of rats. With livers from rats pretreated with recipient-type BMCs, survival of liver allografts was significantly extended, irrespective of irradiation. These results showed that modification of the donor liver by intraportal injection of recipient-type BMCs and concomitant administration of FK506 prior to liver transplantation prolonged liver allograft survival in rats.
