Growth factor levels in a, b maternal plasma, and c, d embryonic brain. VEGF levels (a, c) and basic FGF levels (b, d) were not significantly affected, in either maternal plasma or brain, by polyI:C administration. Results shown are mean ± SEM, *p < 0.05 (ANOVA); ^#p < 0.05 vs WT dams, same treatment (post-hoc Fisher’s test); F values are provided in the Additional file 1. N = 4/group
