PG - 533-9 AB - The adult liver contains hematopoietic stem cells that can reconstitute the bone marrow. We tested whether bone marrow cells (BMCs) derived from liver nonparenchymal cells (LNPCs) can increase the number of hepatocytes within livers. LNPCs from Fischer 344 rats (F344) were infused into the penile veins of F344 congenic Nagase's analbuminenic rats (F344alb) immediately after whole-body irradiation, and the recipients were sacrificed 8 weeks later. Eleven of 15 (73.3%) F344alb that received the LNPC transplantation after irradiation survived, while only 1 of 8 (12.5%) F344alb that received irradiation alone was alive after 8 weeks. Normal albumin gene sequences were detected by PCR in BMCs of the recipient F344alb that received LNPC transplantation after irradiation, indicating that F344alb bone marrow was reconstituted by F344 LNPCs. Although single or pairs of albumin-positive (Alb+) hepatocytes were seen in the liver of untreated F344alb and those with irradiation or LNPC transplantation alone, clusters consisting of >3 Alb+ hepatocytes were detected in the livers of F344alb with the LNPC or BMC transplantation after irradiation together with single or double Alb+ cells. Normal albumin gene sequences were detected by PCR in the DNA isolated from such Alb+ hepatocyte clusters microdissected from the immunostained sections. The data indicate that BMCs derived from F344 LNPCs could increase the number Alb+ hepatocytes within the F344alb liver. CI - Copyright 2006 S. Karger AG, Basel.
