CD34 is expressed in a higher percentage of KLS-EML-HOXB4 cells than in KLS-EML-GFP cells. The percentage of cells that express CD34 is much higher in lineage-depleted EML-HOXB4 cells than in lineage-depleted EML-GFP cells, whereas the percentages of cells that express c-Kit and Sca-1 are similar. The cell surface profiles of the numbered lineage-depleted single-cell clones shown are representative of those of the other lineage-depleted single-cell clones that were used for microarray analyses.
