General and Comparative Endocrinology, 1972
Abstract Electron-microscopic studies indicate that Sertoli cells often possess the fine structure normally associated with steroid-producing tissues. In addition, a Δ 5 -3 β -hydroxysteroid dehydrogenase reaction has been recorded in these cells throughout the vertebrate series.

Morphologie : bulletin de l'Association des anatomistes, 2012
The Sertoli cell is essential for the formation and functioning of the testis. This is the first cell to differentiate into the initially bipotential genital ridge and is the only somatic cell present in seminiferous tubules. Maturation involves the loss of proliferative capacity, formation of intercellular tight junctions and the appearance of some ...

Hepatocyte growth factor modulates Sertoli–Sertoli tight junction dynamics
Journal of Cellular Physiology, 2008AbstractIn mammalian testes Sertoli cells form tight junctions whose function is fundamental for the maintenance of a normal spermatogenesis. Hepatocyte growth factor (HGF) is a cytokine influencing the cellular tight junctions either in normal or in tumor cells.

Sertoli cell testicular tumors
Urology, 1981The testicular Sertoli cell tumor is generally considered a benign tumor that can be treated by orchiectomy and close follow-up. It accounts for less than 1.5 per cent of testis tumors and may be malignant in 10 per cent of cases. Approximately 30 per cent have endocrine activity. We present 5 additional cases to the 75 previously reported in the world

Sertoli cell tumours in the bull
Journal of Comparative Pathology, 1976Abstract Examination of the testes of 1598 bulls slaughtered at abattoirs in north Queensland revealed the presence of Sertoli cell tumours in one mature and five aged bulls. Tumours were present as discrete pale nodules, 1·0 to 3·0 cm. in diameter. They were characterized histologically by a distinct tubular pattern, variable intertubular fibrosis,

Intermediate filaments in sertoli cells
Microscopy Research and Technique, 1992AbstractUsing immunohistochemical techniques both at light and electron microscopic levels, the arrangement and distribution of intermediate filaments in Sertoli cells of normal testis (in rat and human), during pre‐ and postnatal development (in rabbit, rat, and mouse) and under experimental and pathological conditions (human, rat), have been studied ...

Relaxin and Sertoli cell proliferation
Italian Journal of Anatomy and Embryology, 2014Immature Sertoli cells proliferate and several factors affect their number, including the follicle stimulating hormone (FSH), testosterone, estradiol and several paracrine growth factors. Using a primary culture of Sertoli cells isolated from 15-day old Wistar rats we have shown that relaxin stimulates Sertoli cell proliferation through the activation ...

Hormone interactions in the sertoli cells
In Vitro, 1979The effects of follicle-stimulating hormone (FSH) and testosterone in rat Sertoli cells were investigated in vitro by means of isolated cell populations. The Sertoli cells selectively bind FSH, and respond to FSH stimulation with increased accumulation of endogenous cyclic AMP and secretion of androgen-binding protein (ABP).

The Nucleolus of the Apodan Sertoli Cell
Nature, 1948THE association of desoxyribose nucleic acid with the nucleolus has been reported in a number of different types of cells. Hyden1 in nerve cells, Davidson2 in the rat liver cell and Koller3 in tumour cells, find that particles or granules giving a positive Feulgen reaction occur on the periphery of the Feulgen-negative nucleolus.
