Dandelion Extracts Protect Human Skin Fibroblasts from UVB Damage and Cellular Senescence

Figure 7

Dandelion leaf and flower extracts protect H2O2-induced cell ageing. (a) The images showed that H2O2 provokes cell ageing, which is protected by dandelion extracts. The ageing cells had higher gal activity and stained with blue color. HDFs were also incubated with DAPI for nucleus staining for cell counting. Scale bar: 20 μm. (b) was the statistical analysis from (a). HDFs were treated with H2O2 (100 μM) with or without dandelion extracts (300 μg/mL) for 72 hours. The percentage of aged cells was calculated from the number of blue-stained cells to total cells counted. * compared all other groups.
