Validation of gene expression data of CD34 ⁺ cells by real-time RT-PCR. Comparison of gene expression levels by real-time RT-PCR (black bars) and microarray experiments (gray bars) for eight select genes (names indicated at bottom) in CD34⁺ cells of MDS-RARS patients and healthy individuals. Positive and negative fold change values indicate the up- or down-regulation of expression in MDS-RARS patients in relation to the expression in healthy individuals, respectively.
