background: spermatogonial stem cells (sscs), a subset of undifferentiated type a spermatogonia, are the foundation of complex process of spermatogenesis and could be propagated in vitro culture conditions for long time for germ cell transplantation and fertility preservation. objective: the aim of this study was in vitro propagation of human spermatogonial stem cells (sscs) and improvement of ...

the aim of this study was to investigate the in vitro developmental competence of isolated pre-antral follicles derived from vitrified ovaries in the presence of coenzyme q 10 (coq 10 ) . mice pre-antral follicles derived from fresh and vitrified-warmed ovarian tissues were in vitro cultured individually in α-mem medium supplemented with or without coq 10 , followed by adding human chorionic go...

a comparative study was conducted to find a reliable and simple method for evaluation of resistance of sugar beet genotypes to rhizoctonia root and crown rot. for this, 12 sugar beet genotypes were used in greenhouse, field and in vitro experiments. the field experiment was performed in micro plots (1×1×2 meter) using randomized complete block design with 4 replications. prior to planting, the ...

This study was carried out in order to determine the effects of boron and cold stress on pollen germination of almond hybrids in vitro culture, two different media including the absence and presence of boron (0 mg/l, and 100 mg/l) in 10% sucrose and 1% agar medium at 24°C in dark conditions. The results showed that different treatments had a significant effect on the germination percentage. The...

introduction: dental pulp-derived mesenchymal stem cells (mscs) have emerged as a promising tool for use in regenerative medicine. the in vitro growth kinetic and culture requirement of the cells derived from human dental pulp, which is the subject of this present study, is poorly described. materials and methods: stem cells were derived from human third molar and then characterized. the in vit...

Objective: Intravascular catheter-associated infection has been increasing hospitalization in post-surgery patients mainly due to microbial colonization of the catheter surface and formation of a superficial biofilm layer. The present study is aimed in developing an effective antibacterial device which can prevent colonization of organisms by modification of catheter. Methods: In the present st...
