The Involvement of the Androgen Receptor in the Secretion of the Epididymal corpus in the Lizard Podarcis sicula
Figure 2
Changes in the morphology and unchanged expression of AR in the epididymal channel of Podarcis in the natural cycle or in samples treated with E2 during the mating period. (a) Mating period: positive signal for AR-mRNA in the epithelium of the efferent ductules (↑) and corpus (*). (b) Staining with Mallory’s modified trichrome-mating period: note the ciliated cubic cells surrounding the efferent ductules (↑) and the elongated actively secreting cells of the corpusin which lumen is filled with secretory granules (red) and spermatozoa (dark blu). (c) Mating period: positivity for AR-mRNA in the cauda. (d) Winter stasis: both the efferent ductules (↑) and the corpus (*) are still positive. (e) The nonsecretory epithelium of the corpus (*) expresses AR-mRNA also in E2 treated males in the mating period (*). The bar is 30 m.
