Light micrographs of epididymal tubules of wild-type and Fshr^tm1Saco/Fshr^tm1Saco mice. Wild-type (A,C,E) and Fshr^tm1Saco/Fshr^tm1Saco (B,D,F) mice at 3 (A-D) and 6 (E,F) months of age of the initial segment (A,B,E,F) and caput (C,D). Note the full complement of epithelial cells, composed mainly of principal cells (P), in both wild-type and mutants (compare, A,C,E-B,D,F). Also note the presence of sperm within the lumen (Lu) of the tubules in both wild-type and mutants. Tissues were fixed either by glutaraldehyde (A-B) or Bouin's Fixative (C-F). A reduction in tubular size is evident in mutant tubules (B,D,F), as well as the epithelial compartment (B,D,F) compared to wild-type (A,C,E). Immunostaining with an anti-androgen receptor antibody (C-F) revealed a checkerboard staining pattern within the nuclei of principal cells (C-F) comparable between mutant (D,F) and wild-type (C,E). While some nuclei were intensely reactive (arrows), others were moderately reactive (arrowheads) or unreactive (curved arrows). Immunostaining with anti-clusterin antibody revealed a checkerboard staining of principal cells (P) comparable between both wild-type (E) and mutant (F). While some cells stain intensely (arrows), others are moderately reactive (arrowheads) or unreactive (curved arrows). Similar staining was observed in 3 month old mutant and wild-type tissue (not shown). IT, Intertubular space. Original magnification: A-D, 390x; E-F, 250x.
