MRE treatment on human dermal fibroblasts. (a) Cells were treated with methanolic extract at the concentration of 10, 50, 100, and 200 μg/mL for 24 h and 48 h. MRE shows little cytotoxicity towards fibroblasts cells. Values are means ± SD of three replicates from three independent experiments. Significant differences () are denoted by different letters. (b) Cells were incubated for 3 h with 50, 100, and 200 μg/mL of MRE, generating very low amount of ROS. Values are means ± SD of three replicates from three independent experiments. No significant differences were found ( in all cases).
