combination of in vivo cryptorchid testis and in vitro co- culture system to obtain high purification and proliferation of mouse spermatogonial stem cells
نویسندگان
چکیده
background: the present study was designed to evaluate the survival and proliferation of spermatogonial stem cells from cryptorchid mouse testis in co-culture system over a 3 weeks period. materials and methods: sertoli and spermatogonial cells were isolated from bilateral cryptorchid mouse model testes. isolated spermatogonial cells were co-cultured with sertoli cells in minimal essential medium (α-mem) supplemented with 10% fetal calf serum (fcs) for three weeks. the identity of the cells was confirmed through immunocytochemistry against oct-4 and vimentin. results: best results were achieved from the co-culture system spermatogonia which continued to proliferate, and eventually, type a spermatogonia colonies were found. most of the cells in these colonies were oct-4 positive. conclusion: bilateral cryptorchid surgery model is a good model for enrichment of spermatogonial stem cells (sscs). these cells can be used for molecular characterization, genetic manipulation and restoration of male fertility.
