B3. IL-6 level of cells in each group measured by ELISA.

One-way ANOVA was used to compare the mean difference among the three groups. Tukey’s multiple comparisons test was used for post hoc test,

^*p<0.001 between blank group and OGD group,

^**p<0.05 between OGD group and OGD+S group,

^***p<0.05 between OGD+S group and OGD+S+oe-G9a group.
