VREs stimulated endothelial cell migration and tube formation. A Cell migration in HUVECs were examined by transwell assays after HUVECs were plated and cocultured with the bacterial conditioned medium. One representative image from three reproducible experiments is shown. Scale bar, 100 μm. The increasing folds of migrated HUVEC numbers are shown in the bar graph. B HUVECs tube formation were shown in representative images after co-incubating with the bacterial conditioned medium. Scale bar, 200 μm. The increasing folds of tube formation is shown in the bar graph
