Abstract：
:The distribution of F-actin and intermediate filaments in the W/WV mouse was investigated by light and transmission electron microscopy, and fluorescence methods. No spermatogenic cells were detected in the seminiferous epithelium of the W/WV mouse. Its seminiferous tubule was one-half the diameter of that in the normal (+/+) mouse. The Sertoli cell which was an only component of the W/WV mouse seminiferous epithelium was decreased in height, but still retained the polarity as evidenced by light microscopy. The Sertoli cell organelles were similar in appearance when normal and mutant mice were compared. F-actin was recognized at ectoplasmic specialization (ES) of the W/WV mouse Sertoli cell and appeared similar to the normal mouse. However, the junction with ES was more extensive compared with that of the normal mouse Vimentin in the W/WV mouse Sertoli cell was distributed around the nucleus and extended towards the tubular lumen similar to the normal mouse. Its extension within the Sertoli cell trunk, however, was restricted to a lesser degree as compared with that in the normal. Thus, the subcellular Sertoli cell and the distribution of F-actin and intermediate filaments (vimentin) in the W/WV mouse Sertoli cell seemed not to be strikingly affected by lack of spermatogenic cells, suggesting minimal influence of germ cells on Sertoli cell cytology and cytoskeleton.
