Hierarchic clustering analysis of gene expression of 4 ALCL and 3 HD cell lines.

(A) Expression data of 110 genes were selected to optimally separate ALCL and HD. Analysis was performed with GeneSpring software. The unrooted tree of each axis, where the length of the branches represents a similarity in the distance of expression profiles, shows the relationship of the samples (left) and the genes (top). The gene expression values and trust are color-coded as indicated by the scale on the bottom: red indicates the expression level above a median level across all samples, green indicates below the median, and the brightness represents the trust of each value. (B) Enlargement of proportions of the expression profile indicated by stars in panel A. In this matrix, each column represents a sample and each row a gene.
