Estradiol and plasminogen activator secretion by cultured rat Sertoli cells in response to melanocyte-stimulating hormones
Estradiol and plasminogen activator secretion cultured rat Sertoli cells melanocyte-stimulating hormones
2009/2/23
Pro-opiomelanocortin-derived peptides, alpha-MSH and beta-endorphin, are synthesized and secreted by Leydig cells, and are believed to have paracrine effects on Sertoli cells in the testis. Peptid...
Polyamine profiles in rat testis, germ cells and Sertoli cells during testicular maturation
Polyamine profiles rat testis germ cells Sertoli cells
2009/2/23
Polyamine cellular concentrations (putrescine, spermidine and spermine) in the rat testis and testicular cell types were determined by fluorescence spectroscopy of their dansyl derivatives. A met...
Effect of germ cells on vectorial secretion of androgen binding protein and transferrin by immature rat Sertoli cells in vitro
germ cells vectorial secretion androgen binding protein transferrin immature rat Sertoli cells
2009/2/23
The influence of germ cells (greater than 85% pachytene spermatocytes) on vectorial secretion of androgen binding protein (ABP) and transferrin by immature rat Sertoli cells was investigated using t...
Inhibition of ornithine decarboxylase activity by follicle stimulating hormone in primary culture of rat Sertoli cells
ornithine decarboxylase follicle stimulating
2009/2/23
The effect of follicle stimulating hormone on the activity of ornithine decarboxylase (ODC) was determined in primary culture of rat Sertoli cells. Three different FSH preparations (NIH oFSH-S-15, S...
Tonic inhibition of adenylate cyclase in cultured hamster Sertoli cells
cAMP hamster Sertoli cell adenylate cyclase culture pertussis toxin
2009/2/23
Sertoli cells cultured from immature hamsters respond to FSH with a dose-related increase in cAMP accumulation. Pertussis toxin acts synergistically with FSH to stimulate cAMP accumulation. This eff...
Cholinergic inhibition of cAMP accumulation in Sertoli cells cultured from immature hamsters
Sertoli cell cAMP muscarinic receptors FSH hamsters testis
2009/2/23
Acetylcholine inhibits FSH-induced cAMP accumulation in cultured Sertoli cells from immature hamsters. This action of acetylcholine is mimicked by muscarinic cholinergic agonists with a rank order o...
Inhibin production by Sertoli cells during testicular regression in the golden hamster
Inhibin production Sertoli cells testicular regression golden hamster
2009/2/23
The objective of this study was to determine if testicular regression in the hamster results in changes in Sertoli cell function that reflect altered pituitary function. Inhibin-like activity was me...
Transferrin-mediated transcellular transport of 59Fe across confluent epithelial sheets of Sertoli cells grown in bicameral cell culture chambers
Transferrin-mediated transcellular transport 59Fe Sertoli cells bicameral cell
2009/2/23
The transferrin-mediated transcellular transport of 59Fe across confluent epithelial sheets of Sertoli cells grown on Millipore filters was investigated. These filters had been impregnated with reco...
Vitamin A modifies the glycopeptide composition of cultured Sertoli cells
Vitamin A modifies glycopeptide composition cultured Sertoli cells
2009/2/23
Sertoli cells obtained from prepubertal rat testes were cultured in the presence or absence of retinol. Incorporation of monosaccharides and glycopeptide composition of the cells were studied under ...
Effects of neonatal estrogen administration on rat testis development with particular reference to Sertoli cells
neonatal estrogen administration rat testis development Sertoli cells
2009/2/23
An ultrastructural and morphometric study of the testes in 15-, 22-, 45-, and 90-day-old neonatally estrogenized rats was performed. At 45 days of age, the Sertoli cells appeared immature in estroge...
