We evaluated the extent of hepatic fibrosis in chronic liver disease of dogs using a modification of Ishak's staging criteria for human chronic liver disease, and examined the association of stage of fibrosis with immunophenotypic markers of transdifferentiation of hepatic sinusoidal endothelial cells and hepatic stellate cells.
