ELA2 and PR3 expression in CD34⁺ and CD34⁻ populations. Scatterplots showing good correlation of ELA2 (A) and PR3 (B) expression between CD34⁺ and CD34⁻ populations in CML patients before SCT. P values refer to Spearman ρ. Values of genes represent the RQ-PCR expression as a ratio of the gene of interest to the ABL control gene.
