Cell motility array results comparing CD4+CD28^null T lymphocytes (test sample) with CD4+CD28+ T lymphocytes (control sample) testing the expression of 84 different genes. (A) Heatmap performed by calculating the log₂ of the fold change for each gene. The figure represents the level of expression of each gene with a colour scale from dark red (more expression in CD4+CD28^null) to dark blue (less expression in CD4+CD28^null). (B) Representation of the genes with significant expression differences; upregulated genes on the left and downregulated genes on the right. Black bars represent the fold regulation of genes with an expression difference higher than 10, grey bars higher than 5 and white bars higher than 2. The wells corresponding to each gene are in brackets.
