Effects of EGCG on the generation of intracellular ROS in hPDLCs. (A) Representative images of intracellular ROS levels determined by flow cytometry after the cells were treated with EGCG for 72 h (n = 5); (B) Quantitative analysis of intracellular ROS levels (n = 5). Data are presented as mean ± standard deviation. The bars with different lower case letters are significantly different from each other (p < 0.05), and those with the same letter exhibit no significant difference
