Historically, our understanding of molecular genetic aspects of germ cell development has been limited.Recently, results have demonstrated that the derivation of pluripotent stem cells may provide the necessary genetic system to study germ cell development.Here, we first characterized an induced pluripotent stem cells (iPSCs) line, which stably carried an pOct4-EGFP1 recombinant plasmid that expressed green fluorescent protein (GFP) under the control of Oct4 promoter, to confirm the pluripotent characteristic maintained.
