Clustering of gene expression of the STS and AF samples with the RCC gene set (A), OVCA gene set (B), and AF gene set (C). The 12 AF samples and the 25 other STS samples were clustered using the Eisen clustering software Cluster as described in the text. The 16 samples that cluster with AF-1 to AF-5 (open squares) using all 3 gene sets are indicated by open circles. The 6 samples that cluster with AF-6 to AF-12 (solid squares) using all 3 gene sets are indicated by closed circles. The clustering of 3 samples (solid triangles) varied with the gene set. The tissue samples in the tree are joined by very short branches if they have gene expression patterns that are very similar to each other, and by increasingly longer branches as their similarity decreases.
