Figure 3.

Original tissues and corresponding 1-month xenografts were characterized regarding AR expression. Representative samples are shown. Benign original tissues and xenografts were characterized by moderate AR positivity in the nuclei of secretory epithelial cells. CaP tissues and xenografts were characterized by a more heterogeneous expression of AR by epithelial cells. In each case, AR staining intensity and expression pattern of the original tissue were recapitulated in the 1-month xenograft.
