Comparison of the expression level between human and baboon CD34⁺ cells for apparent species-specific genes selected from Table 3.

Representative analysis by semiquantitative RT-PCR for 3 transcripts from Table 3 with apparent species-specific expression as measured on GeneFilters (GF), using primers designed from the 3′-untranslated region of the gene. The PCR reactions were done with (+) or without (−) addition of reverse transcriptase (RT) for the indicated cycle number (Cy). The intensity measured with GeneFilters is compared to that measured by RT-PCR, normalized to genomic DNA. Intensity ratio measurement is shown as positive when expression in humans is higher than baboons, and negative when the reverse is true.
