objective(s): although many researchers have confirmed induction of germ cells from bone marrow mesenchymal stem cells (bmmscs), there are no reports that confirm spontaneous differentiation of germ cells from bmmscs. in this study, we have evaluated the effect of adult sertoli cell condition medium (sccm) as a mutative factor in the induction of germ cells from bmmscs. materials and methods: b...

The production of activin by Sertoli cells isolated from 21-day-old rats was studied using the mesoderm-inducing activity of activin on Xenopus laevis animal cap explants, immunoprecipitation and Western blotting. Furthermore, the effects of recombinant bovine activin-A on rat Sertoli cell aromatase activity and FSH and androgen receptor gene expression were examined. Animal cap explants from X...

The secretions of the Sertoli cell were examined with two polyvalent antisera--one prepared against proteins in rat serum and the other against testis-specific proteins in rete testis fluid. These antisera detected 12 serum and 9 testis-specific proteins in rete testis fluid. To determine the origin of these proteins, primary cultures enriched in Sertoli cells were incubated with [35S]methionin...

PGD2 synthetase (PGD-S; PGH2 D-isomerase; EC 5.3.99.2) is a bifunctional protein first identified in the mammalian brain. It acts as a PGD2-producing enzyme and a retinoid transporter. PGD-S is present in the testis, where its protein and messenger RNA levels are similar to those in the brain. In view of its diversified regulatory functions, we investigated its regulation using primary cultures...

Rat and human Sertoli cells in culture secrete a growth factor, Sertoli cell secreted growth factor (SCSGF). The aims of the present study were (1) to evaluate other testicular cell types as additional sources of SCSGF, as well as their paracrine effect, and (2) to study the hormonal regulation of SCSGF secretion using an A431 cell growth assay. The Sertoli cell was the only testicular cell typ...

sertoli cell tumors of the testis are extremely rare tumors with a heterogeneous pathology. three histological variants have been described: sertoli cell tumor not otherwise specified (nos), large cell calcifying sertoli cell tumor and the sclerosing sertoli cell tumor. the sclerosing sertoli cell tumor described herein is associated with prominent stromal sclerosis. they present as painless sc...

stem cells are generally defined as clonogenic cells capable of both self-renewal and differentiation. probably the best method for long-term preservation of spermatogonial stem cells is cryopreservation. in this study, effects of follicle stimulating hormone and testosterone on viability rate of cryopreserved spermatogonial stem cell after thawing were investigated. sertoli and spermatogonial ...
