In vitro and in vivo differentiation of induced pluripotent stem cells into male germ cells
چکیده انگلیسی
The introduction of induced pluripotent stem cell (iPSC) lines has been a breakthrough in the field of stem cell research. However, the extent of pluripotency among those cell lines tends to be variable due to their different epigenetic signatures. Mouse iPS cell line 4.1 has been established via retroviral transfer of human transcription factors Oct4, Sox2, Klf4, and c-Myc; the germline competence of this line has not been determined. In the present study, we induced the differentiation of miPS-4.1 cells into male germ cells, in vivo and in vitro. In the in vitro model, the behavior of miPS-4.1 cells was identical to that of differentiating mouse embryonic stem cells (ESCs). We obtained primordial germ cell-like cells (PGC-LC) that were positive for alkaline phosphatase (AP) activity. In continuous culture, these cells expressed pluripotent marker Oct4 and male germline markers C-kit and MVH. For our in vivo model, miPS-4.1 cells were co-transplanted with neonatal testicular cell suspension. We observed ectopically reconstituted seminiferous tubule structures, in which the miPS-4.1 cells were homing and developing. In conclusion, we successfully induced the differentiation of miPS-4.1 cells into male germ cells, albeit their epigenetic characteristics. Our study provides a system to examine the mechanisms of male germ cell development and might help to supply an effective treatment for male infertility in the future.
