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 ?4 h to complete.
