Figure 4From: Different effects of rat interferon alpha, beta and gamma on rat hepatic stellate cell proliferation and activationDose dependent effect of IFNs on rat HSC proliferation. Sub-cultured HSCs were incubated with three concentrations of IFNs (100, 500 and 1000 U/ml) for 6 days. WST-1 cell proliferation reagents assayed cell proliferation. The data represent mean ± SEM. HI represents heat-inactivation. * presents p < 0.05 and ** indicated p < 0.01Back to article page
