Figure 4: Changes in BrdU incorporation into immortalized HL1-hT1 cells. Cells were cultured in the proliferation medium without and with different concentrations of alcohol for 4 days. BrdU was added into the cell culture system during the last 4 h of culture. Values are mean ± SEM. N = 4 sets of cell cultures. MCF=mean channel fluorescence. Bars with different letters in each panel are statistically different (p<0.05).
