Comparison of bladder epithelia and whole bladder tissues as controls to bladder cancers. Untutored clusters of whole mouse bladder tissues, epithelia, and tumors were created from hierarchical clustering of the gene expression profiles of each sample. Among the 1554 genes found differentially expressed in mouse cancers compared with epithelia, 51.8% genes were consistent between epithelium and whole tissues as controls. E, bladder epithelium; N, whole bladder tissue; T, bladder tumor.
