abstract：:Activated stellate cells are myofibroblast-like cells associated with the generation of fibrotic scaring in chronically damaged liver. Gene chip analysis was performed on cultured fibrotic stellate cells. Of the 51 human CYP genes known, 13 CYP and 5 CYP reduction-related genes were detected with 4 CYPs (CYP1A1, CYP2E...
