Cell cycle distribution of AML blasts with or without overexpressed cyclin E. In each sample, a total of 10,000 cells were analyzed, and the half peak CV was between 1.5 and 2.6. Histograms show PI-stained cellular DNA. DNA-staining fluorescence intensity on a linear scale (X-axis) and cell number (Y-axis) are represented. The right hand table shows the percentage in G0/G1, S, and G2/M phase. Patients no. 1, no. 2, and no. 3 correspond to respective numbers in Table 2.
