Caption

Spermatid differentiation arrest, germ cell sloughing and apoptosis lead to sterility in the Rbm5^sda/Rbm5^sda males. (A) Intact testes and (B) testis weight of wild-type (WT/WT) and mutant (sda/sda) adult mice (8-week-old). (C) Periodic acid-Schiff stained testis sections at stage VII-VIII and (D) haematoxylin and eosin stained epididymis sections of WT and mutant adult mice. PS: pachytene spermatocyte, rST: round spermatid, eST: elongating and elongated spermatids; Sp: spermatozoa. D, arrowheads indicate sloughed immature germ cells. (E) Caspase 3 (CASP3) and (F) Caspase 9 (CASP9) immunostaining of WT and mutant adult testes. Brown staining represents apoptotic cells. (G) Numbers of Caspase 3 and (H) Casapse 9 positive cells per seminiferous tubule of WT and mutant adult testes. *p<0.01 (unpaired t-test).
