Fig. 4. The abnormalities of spermatogenesis in
Brdt
BD1/
BD1
mice were apparent at the elongating spermatid stage. (A,B)
PAS staining of histological sections of testes from wild-type (A) and
Brdt mutant (B) mice showing the abnormal shape of the elongating
spermatids (B; arrow). (C,D) Immunostaining of histological
sections of testes from wild-type (C) and Brdt mutant (D) mice with
anti-Prm1 antibody, showing that the expression of Prm1 appeared on schedule,
although the morphogenesis of the spermatids was abnormal in the mutants.
