Fig. 4. Cell cycle status of fresh Sca-1+lin− AM+ or AM−cells or total Sca-1+lin− cells. / Fractions of Sca-1+lin− AM+ (black bars), Sca-1+lin− AM− (gray bars), or total Sca-1+lin− cells (horizontal line) were stained with propidium iodide and analyzed on a FACScan flow cytometer for cell cycle status as previously described.23Data are reported as the percentage of cells in G0/G1 phase of the cell cycle (mean ± SEM; n = 6 to 7 for every group). *The presence of statistical significance when the AM− fraction is compared with its AM+ counterpart; P < .05.
