Abstract | OBJECTIVE: METHODS: Porcine hepatocytes and bone marrow mesenchymal stem cells were cocultured in newly developed multi-layer flat-plate bioreactor. Acute liver failure in canine models was induced by D- galactosamine administration.Sixteen canine models were divided into two groups: treatment group (n = 8) and control group (n = 8). Biochemical parameters were determined for 7 days after treatment and liver specimens were collected for histological analysis. RESULTS:
Hepatic encephalopathy and general conditions were significantly improved in the treatment group, but no changes in the control group. Alanine aminotransferase was significantly decreased from (1512 ± 183) U/L to (86 ± 25) U/L in the treatment group, aspartate aminotransferase was significantly decreased from (1472 ± 365) U/L to (46 ± 11) U/ L, lactate dehydrogenase was significantly decreased from (463 ± 76) U/L to (312 ± 84) U/L, total bilirubin was significantly decreased from (28.8 ± 6.2) µmol/L to (12.5 ± 3.6) µmol/L, ammonia was significantly decreased from (56 ± 15) µmol/L to (34 ± 10) µmol/L, and prothrombin time were significantly decreased in the treatment group but increased in the control group, albumin was improved in the treatment group but decreased in the control group. There were 5 canines survived in the treatment group but only 3 in the control group. But there was no difference on survival rates between the two group (P = 0.294). CONCLUSION:
