WebbTo investigate the effect of Sch B on HSC activation, the expression level of α-SMA was measured to determine whether Sch B could inhibit HSC activation against liver fibrosis. As shown in Figure 5A , CCl 4 treatment significantly increased α-SMA-positive cells in the liver as compared to the sham control group, confirming that HSCs were activated in the CCl … Webb1 maj 2004 · A: TNF-α decreases peroxisome proliferator-activated receptor γ (PPARγ) mRNA levels in early primary culture of hepatic stellate cells (HSC). Rat HSC were cultured on 100-mm dishes for 1 day. HSC attached to culture dishes were then treated with TNF-α (20 ng/ml) for 24 h in DMEM containing 1% fetal bovine serum.
