Clustering of individual arrays with respect to genes known to shown differentially-expressed in A- or P-half-sclerotomes. Dendrogram of agglomerative hierarchical clustering of individual array hybridization experiments based upon expression data for genes previously reported to show differentially expression between A- and P-sclerotome-halves. The arrays cluster into two distinct groups, and confirm the original identity of the dissected material as A- or P-half-sclerotome.
