Expression of cytokines in fetal thymi of Hoxa3 +/- Pax1 -/- mice and controls measured by semi-quantitative RT-PCR Each lane contains pooled cDNA from 5–10 E14.5 embryonic thymi of the same genotype. Representative results from one of three experiments for each cytokine are shown. β-actin was used as a control. Panel A, expression of IL-7; Panel B, expression of SCF.
