【Abstract】ObjectiveTo establish an efficient, effective hepatocyte isolation technique in order to increase cell production and decrease the prime cost. Methods The inferior vena cava below diaphragm was dissected and ligatured, and the inferior vena cava below liver was separated. Subsequently, the liver was perfused with EGTA through the portal vein while the inferior vena cava below liver was opened, and then the liver was harvested. The liver tissue was cut into 1 mm×1 mm×1 mm and digested at 37 ℃ water bath with Ⅳ collagenase for 30-40 minutes, then the hepatocytes were purified and cultured in CO2 incubator. The production and function of hepatocytes were assessed. ResultsThe isolated hepatocytes using this technique were more than 95% among the all isolated cells. No statistic difference was found in cell production and cell function comparing with traditional technique. But this technique was simplified and more economically. ConclusionThis modified hepatocyte isolation technique is efficient and effective. It can ensure the amount of production and purity of hepatocytes.
