Open Access Abstract The tight-skin TSK mouse a genetic model of systemic sclerosis SSc develops cutaneous fibrosis and defects in pulmonary architecture. Because hepatocyte growth factor HGF is an important mitogen and morphogen that contributes to the repair process after tissue injury we investigated the role of HGF in cutaneous fibrosis and pulmonary architecture defects in SSc using TSK mice. TSK mice were injected in the gluteal muscle with either hemagglutinating virus of Japan HVJ liposomes containing 8 of a human HGF expression vector HGF-HVJ liposomes or a mock vector untreated control . Gene transfer was repeated once weekly for 8 weeks. The effects of HGF gene transfection on the histopathology and expression of tumor growth factor TGF -p and IL-4 mRNA in TSK mice were examined. The effect of recombinant HGF .
