Fig. 4From: The cytotoxic mechanism of epigallocatechin gallate on proliferative HaCaT keratinocytesEffect of EGCG on the cell cycle profile of HaCaT cells. The differentiated HaCaT cells were treated with the indicated amount of EGCG for 40 h. Cell lysates were subjected to cell cycle profile analysis using flow cytometry in three independent experiments. Data are presented as mean ± SD (n = 3). * p < 0.05; ** p < 0.01; *** p < 0.001 versus untreated cellsBack to article page
