Clustering of gene expression of the STS samples with the RCC gene set (A), OVCA gene set (B), and AF gene set (C). The 25 STS samples were clustered using the Eisen clustering software Cluster as described in the text and are labeled as in Figure 2. 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.
