Hepatic stellate cells (HSCs) have been identified as the main fibrogenic cell type in the liver. Hence, efforts to understand hepatic fibrogenesis and to develop treatment strategies have focused on this cell type. HSC isolation, originally developed in rats, has subsequently been adapted to mice, thus allowing the study of fibrogenesis by genetic approaches in transgenic mice. However, mouse HSC isolation is commonly hampered by low yield and purity. Here we present an easy-to-perform protocol for high-purity and high-yield isolation of quiescent and activated HSCs in mice, based on retrograde pronase-collagenase perfusion of the liver and subsequent density-gradient centrifugation. We describe an optional add-on protocol for ultrapure HSC isolation from normal and fibrotic livers via subsequent flow cytometric sorting, thus providing a validated method to determine gene expression changes during HSC activation devoid of cell culture artifacts or contamination with other cells. The described isolation procedure takes similar to 4 h to complete.
