BACKGROUND In cancer patients, chemo and radiotherapy can cause infertility by damaging spermatogenesis process. This process is based on self-renewal and differentiation of a rare population of the testicular cells called Spermatogonial Stem Cells (SSCs). Scientists have tried to isolate, enrich and culture Human spermatogonial stem cells, hoping to resolve infertility problems in cancer recov...

Background: We have recently shown that human embryonic (hESCs) and induced pluripotent stem cells (hiPSCs) can differentiate into advanced spermatogenic cells including round spermatids by in vitro culture (Easley et al., Direct differentiation of human pluripotent stem cells into haploid spermatogenic cells. Cell Reports 2, 440-446 2012) and also, in collaboration, that rhesus spermatogonial ...

background:   objective: this study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis   materials and methods: isolated testicular cells were cultured in dmem/f12. characteristics of the isolated cells and obtained es-like cell were immune-cytochemically confirmed by examining the presence of plzf, vimentin, oct4 and nanog prote...

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. ...

spermatogonial stem cells (sscs) maintain spermatogenesis throughout life in the male. maintenance of sscs and induction of spermiogenesis in vitro may provide a therapeutic strategy to treat male infertility. this study investigated in vitro differentiation of mouse sscs in presence or absence of sertoli cells, hormones and vitamins. spermatogonial populations were enriched from testes of 4-6 ...

The complex process of spermatogenesis is regulated by various factors. Studies on spermatogonial stem cells (SCCs) have provided very important tool to improve herd genetic and different field. 0.2 to 0.3 percent of total cells of seminiferous tubules is consist of spermatogonial stem cells. To investigate and biomanipulation of these cells, proliferation and viability rate of cells should be ...

BACKGROUND Spermatogonial stem cells are subpopulation of spermatogonial cells in testis tissue that support beginning and maintenance of spermatogenesis. Ubiquitin carboxy-terminal hydrolase L1 (UCHL1) could be a specific marker for identification of spermatogonial stem cells including spermatogonial sperm cells (SSCs) in testis tissue and during the culture; therefore we undertook this study ...
