FIG. 2. Abnormal sperm development in repro5 mutants.

FIG. 2

(A) Wild-type sperm. (B) Sperm from a repro5/repro5 littermate. The phase-contrast images (~60X) of mutant sperm were taken individually, due to low concentration. All have abnormal head shape, and some have abnormal midpieces with a ragged appearance. (C) Wild-type section of an epididymis, with sperm-filled lumens. (D) Section of a repro5/repro5 epididymis. Note the prevalent round cells. (E) PAS-stained section of wild-type testis showing several seminiferous tubules containing elongated spermatids with typical hook-shaped heads. (F) PAS-stained mutant testis section showing multiple seminiferous tubules containing spermatids with abnormally shaped heads. The wild-type and mutant animals were littermates.
