Figure 5: The effect of baicalein on ROS production in CCRF-CEM cells. Cells were stained with DCFDA, followed by flow cytometry analysis 12 h or 24 h post various concentrations of baicalein treatment. The mean fluorescence intensities for ROS generation were tabulated. The data are represented as the mean ± SD in triplicate tests. Similar results were obtained in three independent experiments. * , compared with the untreated control group (0.1% DMSO). ** , compared with the untreated control group.
