Matrix displaying the expression profiles of 159 mmu21 genes (rows) within 190 cDNA libraries (columns). Dendrograms used to reorder libraries (top) and genes (left) are shown, together with eight significant gene clusters (solid bars, left and right of the matrix together with correlation coefficients). The cluster composition is shown with corresponding libraries (A-I and indicated by white arrows at the bottom of the matrix). Coloured dots represent the number of ESTs found in a given library for each gene (see scale). Numbers in red refer to genes prominently expressed in single tissues, listed at the right. Interactive figure and details are given in the Supplementary Information. Gene symbols of human orthologues are used.
