Dynamic regulation of the genes in cord blood CD4⁺ cells during Th17 differentiation. (A) Heatmap presentation of the expression kinetics of the differentially expressed genes between Th17 and Th0 control cells at 2 hours. The genes with signal log ratio > 1 or < −1 are presented. (B) Heatmap presentation of the expression kinetics of the differentially expressed genes at 72 hours. Signal log ratio > 1.5 or < −1.5 was used as cutoff. Gene up-regulation in Th17 culturing condition is shown with red, and down-regulation with blue as indicated with the scales below the heatmaps.
