Introduction: Induction of in vitro spermatogenesis can be useful for infertility treatment in azoospermic patients and those undergoing chemotherapy. Different culture systems have been used to achieve this goal. This review study was performed with the aim to evaluate the application of 3D culture and testicular scaffolds in the establishment of in vitro spermatogenesis. In this review study...
Background and Aims: Testicular ischemia / reperfusion is one of the most serious urological emergencies that is generally identified in men, adolescents and infants. This causes damage to the testicles which, if misdiagnosed and treated improperly, can lead to infertility in men. In the present study, the effects of curcumin and Fe3O4 nanoparticles on the rate of apoptosis and expression of BA...
BACKGROUND Before clinical application, the feasibility and safety of autologous testicular stem cell transplantation should be explored. Apart from limitations in their numbers, spermatogonial stem cells may also be contaminated by malignant cells. Therefore, both enrichment and decontamination before transplantation may be necessary. This study aimed at evaluating the decontaminating potentia...
Previous studies have indicated that there is a relation between testicular function and adequate concentrations of zinc in testicular cells, and that calcitonin alters cellular zinc transfer in the testis. The present studies provide autoradiographic evidence that calcitonin binds in vivo to the cell membrane of testicular Leydig cells. The data thus confirm the presence of the testicular cell...
The aim of this study was to determine correlation of plasma lipids profile with testicular histology parameters in Ross-308 broiler breeder roosters. This study was performed on 12 male ross 308 broiler breeder. Blood samples were collected from a wing vein to measure plasma lipid profiles (cholesterol, triglyceride, LDL and HDL lipoproteins, cholesterol, and glucose). The concentrations of ch...
We have previously shown that non-mammary and tumorigenic cells can respond to the signals of the mammary niche and alter their cell fate to that of mammary epithelial progenitor cells. Here we tested the hypothesis that paracrine signals from mammary epithelial cells expressing progesterone receptor (PR) are dispensable for redirection of testicular cells, and that re-directed wild-type testic...
Healthy specimens of Colisa fasciatus exposed to sub lethal concentration of hexavalent chromium (4.8 mg/L) for 15 days revealed no significant alterations in any testicular architecture during its different phases. However, 30 days exposure revealed distarded shape of lobule and lobular wall, scattered interstitial leydig cells during preparatory phase of testicular cycle where as during spawn...
The testicular vasculature forms a complex network, providing oxygenation, micronutrients, and waste clearance from the testis. The vasculature is also instrumental to testis function because it is both the route by which gonadotropins are delivered to the testis and by which T is transported away to target organs. Whether Sertoli cells play a role in regulating the testicular vasculature in po...
C-kit positive (c-kit(+)) cells are usual tissue-specific stem cells. However, in postnatal testis, undifferentiated spermatogonial stem cells (SSCs) are c-kit negative (c-kit(-)) and activation of c-kit represents the start of SSC differentiation, leaving an intriguing question whether other c-kit(+) cells exist and participate in the postnatal development of testis. To this end, a feasible sy...
