A). Recombinant human LIF inhibited growth of BAE cells in a dose-dependent manner. BAE cells were cultured in the presence of vehicle and indicated concentrations of recombinant human LIF (rhLIF). Cell proliferation was analyzed after 6 days, n=3. Data information: Bars and error bars represent mean±SD. All experiments were carried out in three independent studies. siNegative, negative control siRNA not targeting any known genes. Two-way ANOVA was used as statistical test.
