Purpose: The purpose of this study was the separation of spermatogonial cells from prepubertal NMRI mouse testis by magnetic activating cell sorting (MACS) method and assessment of FBS concentration on surviving these cells after cryopreservation. Materials and Methods: Testes from 6-days-old mouse removed and digested in two enzymatic mediums. First 8-9 min at medium containing collagenase, tr...
This article will provide an updated review of spermatogonial stem cells and their role in maintaining the spermatogenic lineage. Experimental tools used to study spermatogonial stem cells (SSCs) will be described, along with research using these tools to enhance our understanding of stem cell biology and spermatogenesis. Increased knowledge about the biology of SSCs improves our capacity to ma...
objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...
objective: this study presents a simple method for isolation, expansion and purification of neonatal mouse spermatogonial stem cells. methods: we used enzymatic digestion to isolate a cell suspension of spermatogonia and sertoli cells from neonatal 2-day-old mice. the cells were cultured in dmem/f12 that contained 10% serum for two weeks. sertoli and spermatogonia cell characteristics were conf...
In the seminiferous tubules of mouse testes, a population of glial cell line-derived neurotrophic factor family receptor alpha 1 (GFRα1)-positive spermatogonia harbors the stem cell functionality and supports continual spermatogenesis, likely independent of asymmetric division or definitive niche control. Here, we show that activation of Wnt/β-catenin signaling promotes spermatogonial different...
enrichment of cell suspension with germ cells prior to injection into recipient seminiferous tubules is of importance in spermatogonial stem cells (sscs) transplantation. knock-out serum replacement (ksr) has been reported to enhance the proliferation of murine sscs and human embryonic stem cells. the aim of the present study was to investigate the effect of ksr versus fetal bovine serum (fbs) ...
Twenty years ago, the transplantation of spermatogonial stem cells (SSCs) from a mouse to other recipient mice was shown to be feasible, which clearly demonstrated the functional identity of SSCs. Since then, several important new findings and other technical developments have followed, which included a new hypothesis on their cell kinetics and spermatogonial hierarchy in the testis, a culture ...
