Sertoli Cell Quiescence – New Insights
American Journal of Reproductive Immunology, 2012It is currently accepted that the Sertoli cells are proliferatively active only during the embryogenesis and early fetal development, seizing to divide after puberty, when the spermatogenic niche is prepared, and they become terminally differentiated. So far, only seasonal breeders from mammals have been reported as having season‐dependent variations ...

Large-Cell Calcifying Sertoli Cell Tumor
Journal of Urology, 1989We report on a 20-year-old man with a left testicular mass clinically believed to be a malignant neoplasm but subsequently identified as a large-cell calcifying Sertoli cell tumor. This is a rare form of Sertoli cell tumor with unique clinical and pathological features only recently described in the literature.

Germ cell-Sertoli cell interactions
Reproduction, Fertility and Development, 1990The interactions between the Sertoli cells and germ cells are progressively becoming an important part of testicular physiology. This paper explores the cytological basis for these interactions, detailing the cyclic changes in the Sertoli cells in concert with the stages of the seminiferous cycle and the nature of the blood-testis barrier.

The cytoskeleton of terminally differentiated mammalian Sertoli cells is one of the most elaborate of those that have been described for cells in tissues. Actin filaments, intermediate filaments and microtubules have distinct patterns of distribution that change during the cyclic process of spermatogenesis. Each of the three major cytoskeletal elements

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 ...
