Figure 2

Effects of TJE, FTJ, and PEP on cell viability in HDFs. Cells were treated with various doses of TJE, FTJ, and PEP (0, 0.1, and 0.5, 1 μg/mL) for 24 h. The proliferative effects of TJE, FTJ and PEP were evaluated via a WST-1 assay. Data are presented as mean ± standard deviation of three independent experiments. ; vs. untreated group.
