Phenotype Image Detail
Caption Testes from 8 week old wild-type (+/+) and Sycp2tm1Jw/Sycp2tm1Jw (-/-) mice were used for histological and apoptosis analyses. A: Wild-type seminiferous tubule contains a full spectrum of germ cells; spermatogonia, pachytene spermatocytes (PS), round spermatids (RS), and elongated spermatids (ES). B-D: Three types of tubules observed in mutant testis. B: In type I tubules, multiple layers of zygotene-like spermatocytes (arrows) are present. C: In type II tubules, multiple layers of heavily eosin-stained cells (arrows) are present. D: In type III tubules, only a single layer of spermatogonia and Sertoli cells are present. E: Apoptosis of spermatocytes in type II mutant tubules. Arrows indicate one or two layers of brown-stained apoptotic cells. Bars: 50 um.
