Sertoli-Leydig cell tumors belong to the group of sex-cord stromal tumors of the ovary. They account for less than 0,5% of all ovarian neoplasms. The majority of these tumors are benign, and almost all are localised unilaterally. Herewith, we describe an ovarian Sertoli-Leydig cell tumor in an 11-year-old girl.

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 ...

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

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.

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 ...
