Despite extensive research, the mechanisms of prostate carcinogenesis are not well understood. The slow progress in this area is due, at least in part, to lack of a suitable animal model for prostate carcinogenesis. We have developed an ani...

The vascular network of pregnant rabbit ovaries was studied by means of scanning electron microscopy (SEM) of corrosion casts, in order to evaluate the morphofunctional changes of the microcirculation of corpus luteum (CL). Pregnant rabbit ...
Macrophages are present not only in atretic mature follicles but also in the growing follicles of the guinea pig ovary [0.03%]

In atretic ovarian follicles, massive groups of apoptotically dead granulosa cells are eliminated by two kinds of phagocytic cells: intact granulosa cells and macrophages. Using mature guinea pig ovaries, this study further examined whether...
Ultrastructural dynamics of human testicular cords from 6 to 16 weeks of embryonic development. Study by transmission and high resolution scanning electron microscopy [0.03%]
人胚胎发育第六至十六周睾丸生精小管的超微结构动力学研究 透射电镜与高分辨率扫描电镜观察

When the embryo is 6-week-old the gonad is composed mostly of migrating primordial germ cells, surface coelomic mesothelium and mesenchymal cells. At 7 weeks of gestation (wg) testicular cords consist of prespermatogonia, larger, with a mor...
Subsurface crypts and interstitial cells in the ovary of the seal (Phoca vitulina vitulina): light and electron microscopic findings [0.03%]

This morphological study on the ovary of the seal focuses on two structures of special interest: the subsurface crypts and the interstitial cells. Ovaries from 110 seals (from 1,5 months to 12 years) were used. Most of the seals of our stud...
The ultrastructural localization of NADPH-diaphorase enzymatic activity in the Leydig cells of mouse. effects of ethanol administration [0.03%]

Initiation of spermatogenesis is regulated by signals derived from intratubular Sertoli cells as well as extratubular Leydig cells, both being systemic targets of hypophyseal gonadotropins. In addition to Leydig and Sertoli cells, a number ...
