It is widely held that the somatic cell population that is responsible for sperm development and output (Sertoli cells) is terminally differentiated and unmodifiable in adults. It is postulated, with little evidence, that Sertoli cells are not terminally differentiated in some phenotypes of infertility and testicular cancer. This study sought to compare markers of Sertoli cell differentiation i...
Cell Type Specificity of Rhox Gene Expression in Testes To identify the cell types in the testis that express the Rhox genes, we purified testicular cell fractions enriched for Sertoli and interstitial (e.g., Leydig) cells. Although it is not possible to generate entirely pure populations of these cell types, our fractions were substantially enriched, based on the relative levels of Sertoli and...
AIM To assess proliferative and apoptotic potential of the seminiferous epithelium cells in relation to Sertoli cell maturation in newborn rats under the influence of estradiol, follicle stimulating hormone (FSH) or both agents given together. METHODS From postnatal day (PND) 5 to 15 male rats were daily injected with 12.5 microg of 17beta-estradiol benzoate (EB) or 7.5 IU of human purified F...
BACKGROUND The disorders comprising human 'testicular dysgenesis syndrome' (TDS) may be increasing in incidence. TDS originates in fetal life but the mechanisms are not known, and discerning them requires an animal model. METHODS AND RESULTS The study investigated whether male rats exposed in utero to dibutyl phthalate [DBP; 500 mg/kg on gestational days (GD) 13-21] would provide a suitable m...
