Figure 5. Effect of S. haenkei treatment on ROS production on MEFs and human fibroblasts.

ROS generation were measured after 3 hours of incubation in untreated cells and after H₂O₂ exposure. Treatment with NAC was used as positive control. Data are expressed as mean ± SEM percentage of basal (100%) DCF fluorescence intensity (FI) of three independent experiments. **p<0.05 treated vs untreated. (a) ROS production in unstressed MEFs; (b) ROS production in MEFs after exposure to H₂O_2; (c) ROS production in unstressed human fibroblasts; (d) ROS production in human fibroblasts after exposure to H₂O₂.
