Expression of A, transforming growth factor beta 1 (TGFβ1) or B, β-catenin (CTNNB1) after differentiation of ASC. Data is shown as the mean ± SD fold change (undifferentiated/differentiated) ASC for 3 in vivo exposed groups of 0 ppb (green/left), 300 ppb (red/middle), and 1000 ppb (blue/right). Statistically significant groups (N = 3 per exposure group) as determined by One-Way ANOVA (P-value < 0.05) are depicted by the letters atop the bars (i.e. a ≠ b ≠ c).
