Real-time Q-RT-PCR of EGO transcripts derived from human tissues. (A) Fold expression levels of EGO-A in various tissues relative to brain. (B) Fold expression levels of EGO-B relative to brain. CD34⁺ cells and bone marrow mononuclear cell RNA was normalized to the average level of α-tubulin in the tissue panel. UC CD34⁺, umbilical cord CD34⁺; BM CD34+, bone marrow CD34⁺; BMMC, bone marrow mononuclear cells. Standard errors of PCR triplicates are shown.
