. "The murine oct-3 gene encodes a transcription factor containing a POU-specific domain and a homeodomain. In marked contrast to other homeodomain-encoding genes, oct-3 is expressed in the totipotent and pluripotent stem cells of the pregastrulation embryo and is down-regulated during differentiation to endoderm and mesoderm, suggesting that it has a role in early development. The oct-3 gene is also expressed in primordial germ cells and in the female germ line." . . . "Nature" . "Ozato K." . "Poirier F." . "Timmons P.M." . "Rosner M.H." . "Vigano M.A." . "Rigby P.W.J." .
