Abstract: In order to establish a stable primary culture model of hepatocytes in Carassius auratus,3 different isolation methods(tissue culture,mechanical speration and pancreatin digestion) and culture conditions of primary hepatocytes culture were compared in the present study.The survival rate was tested with trypan blue exclusion and the viability was assessed with WST-1;the morphological changes of cells in long-term culture were also observed.The results showed that in tissue culture,hepatocytes migrated from liver and proliferated after 4-5 days,compare with the other methods,it took much longer time for the hepatocytes to move out and it was difficult to collect the cells for further culture.The number and viability of the hepatocytes obtained by mechanical separation were obviously lower than by pancreatin digestion.The liver tissue digested by 0.1% trypsin for 30 min yielded 1.47×108 cell/g(liver weight) and the viability was 91.43%.Both culture medium and concentration of serum influenced the attachment and proliferation of the hepatocytes.The cell cultivated in M199 basal medium supplemented with 10% fetal calf serum at 28℃,4% CO2 for 8-9 days can sub-cultured
