  • Porcine stem cell factor varients and recombinant cells expressing such polypeptides
    Patent number: 6670151
    Abstract: This invention relates to newly identified polynucleotides, polypeptides encoded by such polynucleotides, the use of such polynucleotides and polypeptides, as well as the production and isolation of such polynucleotides and polypeptides. More particularly, the polynucleotides and polypeptides of the present invention have been identified as porcine stem cell factors, and in particular membrane-bound porcine stem cell factors, and still more particularly as being involved in the culture of pluripotent or totipotent porcine cells.
