Hierarchical clustering of the TAM transcriptome in different experiments. Significantly modulated genes from the TAM transcriptome were clustered into a hierarchical representation, generated by the online NCI-MADB facility.²³  Each column represents a particular experiment, whereas each row corresponds to the expression of a particular gene across different experiments. Gene names are indicated on the right. The color bar at the bottom left corner of the diagram correlates the degree of gene expression with the color scheme: up-regulated genes are represented in red, down-regulated genes in green, and unmodulated genes in black.
