Hierarchical clustering of the set of genes that have an association in the literature with the MeSH term 'Cell Adhesion' (that is, appeared in the abstract of at least one article indexed under 'Cell Adhesion'), and were significantly higher (p < 0.01, fold change > 2) either in A549 xenograft tumors over A549 cell cultures or in U118 tumors over cultures. Intensity values were transformed to standard deviations from the average across all twelve profiles. C, culture; T, tumor.
