Comparison of transcript levels of 9 ATG genes in CD34 subpopulations from subsequent IM responders and IM nonresponders. Comparison of transcript levels of 9 ATG genes in CD34 subpopulations, including the stem cell–enriched population (CD34⁺CD38⁻), progenitors (CD34⁺CD38⁺), and mature (CD34⁻) cells from IM responders (n = 6) and nonresponders (n = 6). Values shown are the mean ± SEM of measurements of each transcript normalized to β2M.
