In this study, isolated spermatogonial stem cells (SSCs) and Sertoli cells using enzymatic digestion from patients with maturation arrest of spermatogenesis were grown in Dulbecco's modified Eagle's medium (DMEM) supplemented with 10% foetal calf serum in three different groups: (1) SSCs cultured without Sertoli cells (2) SSCs co-cultured with Sertoli cells(More)
INTRODUCTION A 3D-nanofiber scaffold acts in a similar way to the extracellular matrix (ECM)/basement membrane that enhances the proliferation and self-renewal of stem cells. The goal of the present study was to investigate the effects of a poly L-lactic acid (PLLA) nanofiber scaffold on frozen-thawed neonate mouse spermatogonial stem cells (SSCs) and(More)
OBJECTIVE To evaluate the effect of the demographic/clinical characteristics of patients and testicular histologic findings on the in vitro colonization of human spermatogonial stem cells (SSCs). In vitro isolation and proliferation of human SSCs has emerged as a suitable method for the enrichment of spermatogonia germ cells. METHODS SSCs were isolated(More)
The purpose of this study was (i) To establish in vitro propagation of human spermatogonial stem cells (hSSCs) from small testicular biopsies to obtain a high number of cells; (ii) to evaluate the presence of functional hSSCs in culture system by RT-PCR using DAZL, α6-Integrin, β1-Integrin genes; and (iii) to evaluate the effects of cell concentration on(More)
Proliferation of spermatogonial stem cells (SSCs) in vitro system is very important. It can enhance SSCs numbers for success of transplantation and treatment of infertility in cancer patients. In this study, testicular cells that obtained from azoospermia patients (n=8) by enzymatic digestion were cryopreserved at the beginning and after 2 weeks of culture.(More)
The aim of this research was to find a way to differentiate germ cells from umbilical cord Wharton's jelly mesenchymal stem cells (MSCs) to support in vitro spermatogenesis. A small piece of Wharton's jelly was cultured in high-glucose Dulbecco's modified Eagle's medium in present of 10% foetal calf serum. After the fourth passage, the cells were isolated(More)
Destruction of spermatogonial stem cells (SSCs) along the chemotherapy and radiotherapy is one of the side effects of cancer treatments that lead to infertility. In vitro propagation of hSSCs is necessary to obtain an adequate number of cells for successful transplantation. In this study, hSSCs were isolated from testis biopsies of the patients with(More)
