Immunocytochemical localization of androgen receptor in the comb, uropygial gland, testis, and epididymis in the domestic chicken.
Nuclear, but not cytoplasmic androgen receptors (AR), were localized immunocytochemically in the comb, uropygial (preen) gland, testis, and epididymis of juvenile and adult cockerels. Androgen receptor immunoreactivity (AR-ir) was seen in the comb, in the stratum germinativum of the epidermis and in fibromucoid cells in the dermis in juvenile and adult cockerels. AR-ir was observed in the glandular epithelial (sebum-producing) cells lining the peripheral and middle sections of the tubules in the uropygial gland. AR-ir was not detected in innermost part of the tubules which conduct the sebum to the surface of the skin. AR-ir labeling was not observed in the uropygial gland of juveniles. In the testis, AR-ir was seen in the Leydig cells, in adults but not juveniles. The epithelial cells lining the tubules in the epididymis contained AR-ir in both juveniles and adults.
