Abstract

We describe a technique for isolation and primary culture of bovine hepatocytes, and their metabolic characterization. Hepatocytes were isolated from the caudate lobe of bovine liver by perfusion with 0.25 mM ethyleneglycol tetraacetic acid and 0.05% collagenase. The viability and yield of the cells were 70-92% and 0.1-3.6 x 107 cells/g liver, respectively. When the isolated hepatocytes were cultured in Williams medium E, they began to spread in 3 hr and formed monolayers in 24 hr. These monolayers were retained for at least 6 days. To monitor the metabolic activities specific to liver, synthesis and secretion of albumin were measured by labeling with [35S]-methionine and immunoprecipitation. This activity was low in isolated hepatocytes, but increased after culturing 1-3 days, and decreased again after 6 days. Glycogenolytic activity was also assessed by measuring glucose release to the medium by stimulation with epinephrine. The glycogenolytic response to epinephrine was also enhanced by culturing the hepatocytes 1-3 days, but was decreased after 6 days. Since the isolated bovine hepatocytes retained the liver-specific activities of albumin synthesis and glycogenolysis for several days in culture, these cells are useful for cellular and molecular studies on the functions of bovine liver.
