Figure 4. Hierarchical cluster analysis of immunohistologic data.

Figure 4

The expression patterns of seven proteins CD81, LMO2, HGAL, CD10, BCL6, MUM1/IRF4 (MUM1) and BCL2 in 143 cases of diffuse large B cell lymphoma are shown. Positive staining is indicated in red, lack of staining in green, and uninformative data in black. CD81 protein expression is clustered on the same branch of the dendrogram as the germinal center protein LMO2. Both CD81 and LMO2 cluster together with other germinal center proteins, HGAL, BCL6, and CD10 (colored orange), and away from non-germinal center proteins, MUM1 and BCL2 (colored blue).
