Abstract

Hepatocyte transplantation has excited much interest in lending temporary metabolic support to a failing liver following acute liver injury. The exact site from which they act and the clinical, biochemical, and histological changes in the recipient body following hepatocyte transplantation is yet to be worked out. The present study is an attempt to delineate location and function of transplanted hepatocytes and alsothe overall survival of these cells with a fluorescent in situ hybridization (FISH) technique using a Y-chromosome-specific probe in a carbon tetrachloride (CCl4)-induced mice model of fulminant hepatic failure. Fifty-five syngenic adult Swiss female mice of approximately the same age and body weight were divided into three groups. Group-1 (n = 15), which received mineral oil, served as a negative control. Group-II (n = 15) received CCl4 (3 mL/kg) 40% vol/vol in mineral oil, by gavageserved as positive control for hepatic failure. Group-III(n = 25) received intrasplenic transplantation of syngenic single cell suspension of hepatocytes in Hanks medium, after 30 h of CCl4 administration MaleSwiss adult mice (il = 15) served as donors of hepatocytes. The overall survival of animals in groups I to III was 100, 0, and 70%, respectively, by 2 wk of the study period. Transplanted hepatocytes were identified by Periodic Acid Schiff (PAS) staining and confirmed with a FISH technique using the Y-chromosome probe. The majority of exogenously transplanted hepatocytes were found in the liver and spleen sections even after 1 wk of hepatocyte transplantation. Transplanted cells were mostly found to be translocated into the sinusoids of the liver. Transplanted hepatocytes were found to be beneficial as a temporary liver support in a failing liver, significantly improving the survival of theanimals. In the present study, the FISH technique was used to unequivocally distinguish the transplanted cells from the host, and thus describes a model for studying the distribution and survival of the transplanted cells.
