Culture of bovine hepatocytes: a non-perfusion technique for cell isolation

In this work we have studied the isolation and culture of mature bovine hepatocytes on plastic dishes without exogenous matrix. The liver has been disaggregated in a collagenase solution instead of undergoing a perfusion step. After a few days in culture, the plates showed several clusters of different cell types. Although the average yield was 1.60±0.57×108 viable liver cells per gram of tissue, these cultures were formed by non-parenchymal cells and only very few or none by parenchymal cells. In these cultures, actin structures used as a marker for Stellate (Ito) cells have been visualized by immunocytochemical techniques. In order to increase the proportion of parenchymal cells a centrifugation on Percoll, which separates cell sub-populations, has been introduced. Though the yield was lower than in the previous method, these pre-purified cultures were only composed of hepatocytes. It has been shown that these cells exhibited albumin synthesis, which is a specific hepatocytes function. In addition, these cultures were capable of producing metabolites of 7-ethoxycoumarin at a higher rate than non purified cell cultures. Therefore this simplified procedure for the isolation and culture of functional and viable hepatocytes may be applied for in vitro studies in bovine.
