In vitro propagation of spermatogonial stem cells from KM mice.

Comparison of Neonatal and Adult Mice-derived Sertoli Cells in Support of Expansion of Mouse Spermatogonial Stem Cells In vitro

O-19: Proliferation of Small Population of Spermatogonial Stem Cells in Azoospermic Patients

Background: With treatment success in young boys with cancer, long-term effects of cancer treatment have found importance in pediatric oncology. Temporary or permanent infertility after treatment is an important subject in childhood and adult cancer patients which decrease quality of life. The one approach to overcome infertility in these cases is to cryopreserve small biopsy testicular tissue ...

The Effects of Plla Nanofiber Scaffold on Proliferation of Frozen-Thawed Neonate Mouse Spermatogonial Stem Cells

Purpose: To investigate of the effects of a poly L-lactic acid (PLLA) nanofiber scaffold on proliferation of frozen-thawed neonate mouse spermatogonial stem cells.Materials and Methods: Spermatogonial cells were isolated from neonatal 3-6-day-old NMRI mice testes by two steps enzymatic digestion and differential plating. The isolated spermatogonial cells were divided into four culture groups: 1...

Melatonin improves spermatogonial stem cells transplantation efficiency in azoospermic mice

Objective(s):Transplantation quality improvement and reduction of cellular damage are important goals that are now considered by researchers. Melatonin is secreted from the pineal gland and some organs such as testes. According to beneficial effects of melatonin (such as its antioxidant and antiapoptotic properties), researchers have proposed that the use of melatonin may improve transplantatio...

Establishment of Oxidative Stress Modeling during Spermatogonial Stem Cells Cultivation Treated with Different Doses of H2O2

Introduction: Nowadays, spermatogonial stem cells (SSCs) cultivation has been used by many researchers as an effective tool for infertility treatments. Oxidative conditions can be effective on cell proliferation and differentiation of these cells. So, the aim of this study was to establish oxidative stress model for antioxidant activity of some drugs investigation during SSCs in vitro culture. ...

An Efficient In Vitro Culture System To Amplify Spermatogonia Stem Cell Markers

Background: Proliferation of spermatogonial stem cells (SSCs) can be a treatment for infertile men. Here, we design an efficient method based on culturing in the presence of Sertoli cells to improve the expression level of some specific spermatogonia stem cell genes during two weeks post culture. Materials and Methods: Cells were derived from neonatal (2-6 days old) mice testes and were cultur...
