Inhibin B levels in plasma of the male rat from birth to adulthood：effect of experimental manipulation of Sertoli cell number
Inhibin B levels male rat experimental manipulation Sertoli cell number
<
2009/2/18
Sertoli cells undergo important changes in their number and function at different ages in the rat and may be the primary source of circulating inhibin B. The aims of this study were 1) to establis...
Evidence for the regulation of prostatic oxytocin by gonadal steroids in the rat
Testosterone dihydrotestosterone 5a-reductase finasteride
<
2009/2/18
Oxytocin and its receptor are present in the mammalian prostate, and the peptide has been shown to increase prostatic growth, 5alpha-reductase activity, and contractility. This study was performed...
Hormonal regulation of inhibin B secretion by immature rat sertoli cells in vitro：possible use as a bioassay for estrogen detection
Male reproduction estrogens
<
2009/2/18
The influences of follicle-stimulating hormone (FSH), gonadal steroids, and culture time were studied in relation to inhibin B production by Sertoli cells of immature rats cultured in vitro. Serto...
The primary culture of rat prostate basal cells
primary culture rat prostate basal cells
<
2009/2/18
The objective of this study was to identify the cells from rat prostate epithelium that attach and proliferate in primary culture. Minced ventral prostate was dissociated by DNAse/collagenase dige...

The peripheral distribution of Sertoli cell F-actin, a cytoskeletal protein found in Sertoli cell ectoplasmic specializations, is associated with enhanced spermatid binding to the Sertoli cell and...
Androgen binding protein secretion and endocytosis by principal cells in the adult rat epididymis and during postnatal development
Androgen binding protein secretion endocytosis principal cells adult rat epididymis
<
2009/2/18
Androgen binding protein (ABP) has been shown to be secreted by Sertoli cells and to be actively taken up by the efferent ducts and proximal caput epididymidis and, yet, to be present at high concen...
Apoptosis pattern elicited by several apoptogenic agents on the seminiferous epithelium of the adult rat testis
Apoptosis pattern apoptogenic agents seminiferous epithelium adult rat testis
<
2009/2/17
Spontaneous germ cell death during spermatogenesis is an important event, and the usefulness of the seminiferous epithelium as an in vivo model to study apoptosis has been evidenced. Nevertheless, the...
The loss of alpha-adrenergic effect during the erectile response in the long-term diabetic rat
Diabetic rats erectile response nitroglycerin phenylephrine
