Broad tumor clusters are highlighted with names corresponding to the major human subtype(s) found within each. (B) Clustering location of all tumors as displayed by their human subtype or mouse class. (C) Basal gene cluster. (D) Proliferation gene cluster. (E) Normal breast gene cluster. (F) Claudin-low subtype high expression gene cluster. (G) Luminal gene cluster.
