Expression of endothelial and mesenchymal markers in endothelial cells. α-SMA (A), VIM (B) and VE-CAD (C) gene expression. The analysis was performed in HUVEC endothelial cells as described in Figure 5, Graphs represent mean ± standard deviation (error bars)(n = 6 biological replicates) (A) CTR vs. PHY 2.27% p < 0.0001, (B) CTR vs. PHY 1.36% p < 0.0001, CTR vs. PHY 2.27% p < 0.0001, PHY 1.36% vs. Xylo LS p = 0.0086, PHY 2.27% vs. Xylo MS p = 0.0023, (C) CTR vs. PHY 1.36% p = 0.0019, CTR vs. PHY 2.27% p = 0.0016, PHY 1.36% vs. Xylo LS p = 0.0013, PHY 2.27% vs. Xylo MS p = 0.0036 * p < 0.05, ** p < 0.001.
