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 cryptorch id
mouse model testes. Isolated spermatogonial cells were co-cultured with Sertoli cells in minimal
essential medium (a-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 crypto rchid surgery model is a good model for enrichment ofspermatogonial
stem cells (SSCs). These cells can be used for molecular characterization, genetic manipulation and
restoration of male fertility.
