The complex process of spermatogenesis is regulated by various factors. Studies onspermatogonial stem cells(SCCs)have provided very important tool to improve herd geneticand different field. 0.2 to 0.3 percent of total cells of seminiferous tubules is consist ofspermatogonial stem cells. To investigate and biomanipulation of these cells, proliferationand viability rate of cells should be increasedin vitro, at first. Follicle stimulating hormone(FSH) has been suggested to play a determinant role in the survival of germ cells in additionto increasing spermatogonial proliferation. In this study, thein vitroeffects ofFSHonspermatogonial cell colony formation were investigated. Sertoli and spermatogonial cellswere isolated from 3-5 months old calves. The identity of theSertoli cells and spermatogonialstem cells were confirmed through immunocytochemistry and colony morphology,respectively. Co-cultured Sertoli and spermatogonial cells were treatedwithFSHin differentdose of10, 20 and 40 IU mL-1FSH, before colony assay.Results indicated that,FSHincreasedin vitrocolonization of spermatogonial cells in comparison with control group. In conclusion,usingFSHprovided proper bovine spermatogonial stem cell culture medium forin vitrostudy of these cells. |
