Immature rat seminiferous tubules reconstructed in vitro express markers of Sertoli cell maturation after xenografting into nude mouse hosts.
Sertoli cells undergo a maturation process during post-natal testicular development that leads to the adult-type Sertoli cell, which is required for spermatogenesis. Understanding Sertoli cell maturation is therefore necessary to gain insight into the underlying causes of impaired spermatogenesis and male infertility. The present study characterized the cellular and molecular differentiation of...
متن کاملIsolated rat seminiferous tubules synthesize guanidoacetic acid and creatine from arginine
Creatine is synthesized in a two-stage process, involving transfer of the amidine group of arginine to glycine to form guanidoacetic acid, which is subsequently methylated to creatine. The first report of testicular creatine synthesis was made by Alekseeva & Arkhangel'skaya (1964) based upon experiments in which whole testicular tissue was incubated in vitro with [ 14C]glycine. These findings w...
متن کاملO-6: Maturation of Spermatogenic Cells in Artificial Seminiferous Tubules
Background This study aimed to investigate whether Artificial Seminiferous Tubules (AST) coated with testicular extra cellular matrix (ECM) support maturation of spermatogenic cells from immature testes. MaterialsAndMethods Medical grade tubes coated with testicular ECM were used. Testes from immature mice were loaded in the concentration of 10000- 20000/ml. Tubes were then immersed in germ cel...

Objective(s): The present study aimed to assess the in-vitro efficacy of nanoparticulate calcium sodium phosphosilicate mouthwash in the obstruction of dentinal tubules.Materials and Methods: This in-vitro, study was conducted on 120 sections obtained from extracted human premolars, which were etched with citric acid for two minutes and rinsed with distilled water. Afterwards, the section...
متن کاملby isolated rat renal tubules
1. The effect of glucocorticoids on the deiodination of thyroxine (T,) to 3,5,3’-trbiodothyronine (T,) was studied in rat renal tubules prepared by collagenase digestion. 2. In short-term (6 h) experiments, cortisol and dexamethasone inhibited the conversion of T, into T, at concentrations of 2 x lo-, moll1 and 2 x mol/l respectively. The inhibition by cortisol and dexamethasone was time depend...
