Abstract Background The activation of hepatic stellate cells HSCs plays a pivotal role during liver injury because the resulting myofibroblasts MFBs are mainly responsible for connective tissue reassembly. MFBs represent therefore cellular targets for anti-fibrotic therapy. In this study we employed activated HSCs termed M1-4HSCs whose transdifferentiation to myofibroblastoid cells named M-HTs depends on transforming growth factor TGF -p. We analyzed the oxidative stress induced by TGF-P and examined
