title: Bone marrow mononuclear cell transplant therapy in mice with CCl4-induced acute liver failure.
abstract: OBJECTIVE
  Stem cell transplantation has theoretical potential for the treatment of certain liver diseases. However, the use of bone marrow mononuclear cells as a therapy for liver disease has received little attention. The present study was to examine whether bone marrow mononuclear cells might be useful in the management of acute liver failure in an animal model. MATERIALS AND METHOTS: Bone marrow mononuclear cells were harvested from BALB/c mice and then labeled with the fluorescent dye PKH26. The labeled cells were subsequently infused into the tail veins of mice in which hepatic injury had been induced by CCl4 toxicity. After transplantation, the labeled cells in the liver were studied by fluorescent microscopy, and the levels of proliferating cell nuclear antigen and albumin were quantified in bone marrow mononuclear cell-treated and untreated groups. Serum aminotransferase activity was also monitored at various time points post-liver injury.
  
  
  RESULTS
  Transplanted bone marrow mononuclear cells labeled with PKH26 were found to populate the damaged liver around the portal and centrolobular regions, and they appeared to differentiate into albumin-producing hepatocyte-like cells. Animals that received bone marrow mononuclear cells also showed a trend toward improved liver enzymes as well enhanced survival rates, relative to controls.
  
  
  CONCLUSIONS
  These findings suggest that systemically delivered bone marrow mononuclear cells may relocate to and be retained by the injured liver; transplantation of bone marrow mononuclear cells showed an overall beneficial effect in a murine model of acute liver failure.
