Effect of the Taraxacum officinale (TO) methanol extract on LPS-induced monocyte adhesion to HUVECs. HUVECs were pretreated with TO extract (100 μg/ml) for 1 h, and then stimulated with 1 μg/ml LPS for 24 h. Adhesion of fluorescent THP-1 monocytes was photographed by fluorescence microscopy (a) and analyzed (b). Scale bars: 1000 μm. Results shown are the mean ± SE of 3 independent experiments. **p < 0.01 vs LPS only treatment
