Immunohistochemical staining for progesterone receptor A and B. Representative pictures of immunohistochemical staining for progesterone receptor A and B (PGRA and PGRB) expression in tissue microarray cores from prostate cancer prostatectomy specimens in addition to positive and negative control tissue. Microscope pictures taken with 15x magnification. PGRA panel: (A) low and (B) high stromal PGRA expression in a normal tissue core, (C) low and (D) intermediate - high stromal PGRA expression in a tumor tissue core, (E) negative tissue control in normal human brain tissue (F) positive tissue control in normal human endometrial tissue. PGRB panel: (A) low epithelial PGRB expression and low – intermediate stromal PGRB expression in a normal tissue core, (B) high epithelial PGRB expression and intermediate – high stromal PGRB expression in normal tissue core, (C) low – intermediate epithelial PGRB expression and low stromal PGRB expression in tumor tissue core, (D) high epithelial and stromal PGRB expression in a tumor tissue core, (E) negative tissue control in normal human brain tissue (F) positive tissue control in normal human endometrial tissue.
