Figure 2From: Gene expression signatures of morphologically normal breast tissue identify basal-like tumorsHierarchical clustering and heatmap showing the segregation of samples by tissue type. (a) Hierarchical clustering of normal tissue samples shows segregation by tissue type (red, adjacent epithelium; blue, reduction epithelium; green, adjacent stroma; orange, reduction stroma). (b) Heatmap showing tissue specific gene expression clusters.Back to article page
