Between June 85 and December 87, 69 testicular biopsies were submitted for histopathological examination during investigation of infertility; ten (14%) patients had a Sertoli cell only syndrome. The history, clinical features, and hormonal profiles were analyzed in an attempt to categorize these patients on aetiological basis. Two followed treatment of malignancy--one by radiation for testicula...

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...

background: the anticancer agent imatinib (im) is a small molecular analog ofatp that inhibits tyrosine kinase activity of platelet derived growth factors (pdgfs)and stem cell factor (scf) receptor in cancer cells. however these factors have a keyrole in regulating growth and development of normal sertoli, leydig and germcells.objective: the aim of this study was to determine cell viability, pd...

The three-dimensional structure of the Sertoli cell in the miniature "shiba" goat was examined using scanning electron microscopy. In the basal portion of the seminiferous epithelium, spermatogonia and/or spermatocytes were located in compartments enclosed by adjacent Sertoli cells. From the basal aspect, they were situated in successive recesses. In the middle portion, early round spermatids h...

One of the newest methods to reduce cerebral ischemia damages is cell therapy. The aim of this study is to evaluate the effect of Sertoli cell transplantation on ischemia-induced injuries in animal models of stroke. Rats were divided into four groups: transplant+ischemia, ischemia, sham, and control. Sertoli cells were separated from the other testis of rats and cultured. Unilateral Sertoli cel...

Dye coupling experiments were performed to determine whether the gap junctions connecting Sertoli cells with other Sertoli cells and different germ cell stages in rats showed functional variations. Chop loading of adult rat seminiferous tubules was conducted using fluorescent dextran controls and a variety of low-molecular-weight tracers (lucifer yellow, biotin-X-cadaverine, biotin cadaverine, ...
