Ontogeny of androgen receptor-like immunoreactivity in the reproductive tract of male Monodelphis domestica.
The distribution of nuclear androgen receptor-like immunoreactivity was studied in the reproductive tract of the developing and adult gray short-tailed Brazilian opossum (Monodelphis domestica), using the well-characterized rabbit polyclonal androgen receptor antibody, PG21. Androgen receptor-like immunoreactivity was first detected on the fifth day of postnatal age, in the mesenchymal tissues of the ductus deferens, gubernaculum testis, inguinal, and scrotal areas; the urogenital sinus; and the genital tubercle. Androgen receptor-like immunoreactivity was first seen in the interstitial cells of the epididymis at 45 days of age; the testes developed androgen receptor-like immunoreactivity at 60 days of age. The epithelium of prostatic glands contained androgen receptor-like immunoreactivity only in the adult. The presence of androgen receptor-like immunoreactivity during development correlated well with the known androgen dependence of the differentiation of most reproductive organs.
