  The main purpose of the present study was to investigate the treatment of male infertility, because infertility treatment is important in the group of cancer patients treated with gonadotoxic drugs. The main approach of the mentioned study is to compare two different groups of spermatogonia stem cell culture methods and to evaluate the efficiency of differentiation and proliferation of these group of cells. Successful transplantation of spermatogonia stem cells (SSCs) in laboratory studies requires a suitable microenvironment for proliferation and differentiation of these cells. The natural extracellular matrix provides a good environment for stem cell culture. In the present study, themain purpose was to evaluate the ability of spermatogonial stem cells proliferation and differentiationvia the utilizing the microfluidic device (ex vivo). On the other hand, in the present study, we compared the obtained resultswith culture conditions in conventional culture plates (in vitro) to compare the SSCs proliferation and differentiation ability. In in-vitro culture method first spermatogonia stem cells from neonatal mice were isolated, then the resulted cells were seeded in culture plates on a scaffold consisting of hyaluronic acid, chitosan and decellularized testicular tissue, furthermore, in ex-vivo study the extracted spermatogonial stem cells were cultured in the microfluidic system without a scaffold. In ex vivo study, spermatogonial stem cells were extracted from neonatal male NMRI mice. The extracted cells were transferred to a microfluidic chip that was designed without an external pump, thereafter, the culture process was evaluated by IHC evaluation after one-month culture. In examined samples, cell attachment to the seminiferous tubules, DAPI staining and immunohistochemistry were evaluated. The results of immunohistochemical studies showed a significant increase in the expression of PLZF and TEKT1 markers in ex-vivo models. Finally, the results revealed that the ability of spermatogonia stem cells to induce spermatogenesis and production of haploid cells under testicular tissue culture in the microfluidic system is much more significant than conventional culture conditions in laboratory plates for these cells.
