Nine candidate genes are consistently expressed in the E-SLAM fraction versus the lineage negative fraction of BM and FL blood cells. (A) Quantitative real-time PCR analyses of transcript levels in extracts of 300 to 400 E-SLAM cells (red bars) or 10⁴ lin⁻ (white bars) from FL. (B) Quantitative real-time PCR analyses of transcript levels in extracts of 300 to 400 E-SLAM cells (blue bars) or 10⁴ lin⁻ (white bars) from adult BM. All values are normalized to Gapdh. Values shown are the mean ± SEM of values obtained in 3 to 6 independent experiments, with each measurement being derived from triplicate assays. N.D. indicates not done.
