Abstract

Oocyte-like cells (OLC) can be generated by stem cells after the induction and differentiation in vitro, and maturated when transplanted in vivo to improve the development potential. Human amniotic fluid stem cells (hAFSC) were cultured for 10 days in porcine follicle fluid (pFF) that was extracted from the medium follicle with high levels of hormones and Bmp 15 protein. After the induction, the cell aggregates showed the germ cell-like cells and produced the germ cell marker oct4, and triggered epigenetic changes with high expression of methylation transferase gene dnmt3b. The cell aggregates were packaged into porcine theca folliculi to form grafts, which were then transplanted into mouse renal capsule. After one month of transplantation, the morphology of OLC from a graft was not only similar to oocytes, but also expressed the germ cells markers (oct4, nanog, stella, ifitm3, dazl, nanos3, bmp15, and gdf9). The results demonstrate that the in vivo differentiation model was useful for OLC development.
