Fig. 1. The viability and morphology of DF-1 cells in the poly(I:C)-treated conditions with various concentrations of poly(I:C) for 24 h.

The statistical analysis was performed to assess statistical significance between each concentration and the non-treated control. Error bars were expressed as SEM ^*p < 0.05, ^**p < 0. 01, ^***p < 0.001.
