Fig. 4. Phase-contrast microscopy of whole testes and pre-individualization stages of spermatogenesis of wild-type and Pros{alpha}6T1 mutant males. (A,C) Wild-type and Pros{alpha}6T1 testes. (B,D) Higher magnification of the seminal vesicle in A and C (boxed), respectively. (E-L) Comparison of different spermatogenic stages of wild-type (E-H) and Pros{alpha}6T1 (I-L) testes. (E,I) Primary spermatocyte cysts at the 16-cell stage. (F,J) Onion (64-cell) stage spermatid cysts. (G,K) Early stage of elongating spermatid cysts. (H,L) Fully elongated spermatid cyst bundles. Scale bars: 150 µm in A-D,H,L; 10 µm in E-G,I-K.
