چکیده مقاله:

Background: Spermatogonial stem cells (SSCs) are responsible for the propagation of a father’s genetic material by spermatogenesis. As well, SSC is intended for the treatment of infertility and other purposes, including correction of inherited disorders. Also SSCs can produce embryonic-like stem cells in vitro which could be used as an alternative for therapeutic, diagnostic cases and therefore, improve techniques to manipulate them in vitro as a prerequisite to achieve the mentioned goals. In this study, we sought to optimize culture conditions to maintain the survival and self-renewal of these cells. Recent studies show that inhibition of p53 has positive effect on the viability in some stem cells.Methods: Germ stem cells extracted from newborn mouse testis then the appropriate concentration PFT-μ, inhibitor of p53 located on mitichondria, determined using the MTT assay and the cells were treated with optimal concentration, then apoptosis was assessed by testing Annexin-V / PI in cells treated with optimal amounts of PFT-μ.Result: The results showed that cell apoptosis at optimal concentrations decreased in compared with the control group.Conclusion: PFTμ by inhibiting of p53 located on mitochondria release of Bcl2 and inhibit stems cell death. So spermatogonial cells apoptosis expected to be reduced in the presence PFTμ .
