title: Stage-dependent variation in the rat Sertoli cells nuclear volume.
abstract: A morphometric study was carried out to investigate stage-dependent variation in sertoli cell nuclear volume in the rat testis. sertoli cell nuclei had the largest volumes in stages IX to X of the seminiferous epithelium cycle (746 microns3), and the smallest volumes in stage XIV (624 microns3). In the remaining stages, the nuclei presented intermediate values, without significant differences. The results were discussed in terms of a possible functional cyclic variation in the sertoli cell reflecting changes in their nuclear size.
