C). The JAK inhibitor baricitinib reversed LIF-induced BAE growth inhibition. BAE cells pre-incubated with inhibitors for 1 hour were treated with vehicle and LIF (10 ng/ml, Sigma). Cell proliferation was analyzed after 6 days using alamar blue, 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.
