 en Derivation of ES-like cell from neonatal mouse testis cells in autologous sertoli cells co-culture system
Asadi, Mohammad Hossein; Javanmardi, Setareh & Movahedin, Mansoureh


Background: Spermatogonial stem cell (SSC) is a self-renewing population of male adult stem cell. SSCs have a differentiation potential which are similar to embryonic stem cells. These Embryonic stem like (ES-like) cells can be a potential source for pluripotent cells for stem cell-based therapy.
Objective: This study presents an economical and simple co-culture system for pluripotent stem cells generation from neonatal mouse testis
Materials and Methods: Isolated testicular cells were cultured in DMEM/F12. Characteristics of the isolated cells and obtained ES-like cell were immune-cytochemically confirmed by examining the presence of PLZF, vimentin, Oct4 and Nanog protein. Expression of the pluripotency and germ-cell specific genes was analyzed by qPCR in derived ES-like colony and SSCs respectively.
Results: The experiment results indicated that our method of obtaining pluripotent ES-like cells from spermatogonial cells (SCs) is simpler than the described methods. ES-like cells were immunopositive for pluripotency markers. ES-like cell qPCR results indicated significant increase in pluripotency genes expression and significant decrease in germ cell-specific genes expression.
Conclusion: The results indicated that ES-like cell with pluripotency characteristic were generated from freshly isolated spermatogonial cells. The pluripotent stem cells provide a cellular reservoir usable for regenerative medicine instead of embryonic stem cells.
