Isolation and Culture of Adult Mouse Hepatocytes

Abstract

The liver performs a multitude of functions including the regulation of carbohydrate, fat, and protein metabolism, the detoxification of endo- and xenobiotics, and the synthesis and secretion of plasma proteins and bile. Isolated hepatocytes constitute a useful technique for studying liver function in an in vitro setting. Here we describe a method for the isolation of hepatocytes from adult mouse liver. The principle of the method is the two-step collagenase perfusion technique which involves sequential perfusion of the liver with ethylenediaminetetraacetic acid and collagenase. Following isolation, the cells can either be used for short-term studies or, alternatively, maintained in culture for prolonged periods to study long-term changes in gene expression. The protocol for mouse hepatocyte isolation may be applied to both normal and transgenic mice.
