Compartmentalized expression of AR (A,B) and ER (C,D) quantified by means of the labeling index (LI) computed in stroma (X-axis) and epithelium (Y-axis) from non-tumour (A,C) and tumour tissue samples (B,D). Each symbol identifies a PCa patient classified with respect to the Gleason score of the tumour (see graph legend). The diagonal indicates equal expression in epithelium and stroma.
