CFSE dilution of H2O2 treated cells at 24, 48 and 72-h post-release. Cell proliferation was observed by labelling cells with the cell permeable fluorescent dye CFSE and monitoring its dilution over 72 h for control and treatment. At each cell division, the fluorescence is roughly halved, enabling the visualization of the proliferation of labelled cell populations over time. The number of cells is displayed on the y-axis and the concentration of CFSE is on the x-axis. Graph shows the results from a representative experiment
