  • Patent number: 6429293
    Abstract: The present invention provides inter alia, isolated “sculpin-type intracellular AFPs” from shorthorn sculpin and their corresponding nucleic acids. The sculpin-type intracellular AFPs are alanine-rich polypeptides that are synthesized in the peripheral tissues such as the skin and gills of fish. These skin-type AFPs are encoded by a distinct set of AFP genes that lack a signal peptide, which is indicative of their intracellular location. The polypeptides are used to make cells cold resistant and to improve the palatability of cold foods and liquids. Cold resistant eukaryotes and prokaryotes, including plants, animals and bacteria are made using the sculpin-type intracellular antifreeze polypeptides and nucleic acids. Moreover, the present invention provides methods for preserving cells, tissues and organs ex vivo using the AFPs described herein.

  • Patent number: 6353150
    Abstract: There is disclosed a chimeric mammal having a stable bone marrow graft of human hematopoietic cells capable of differentiating into multiple lineages of human mature cells, wherein at least 30% of the hematopoietic cells in the mammal's bone marrow are of human origin. The inventive method comprises sublethally irradiating an immunodeficient mammal, infusing human hematopoietic cells into the mammal and administering an effective amount of human mast cell growth factor (MGF) and a human granulocyte macrophage colony stimulating factor/interleukin-3 fusion protein (GM-CSF/IL-3 FP) to promote engraftment of human cells within the chimeric mammal's bone marrow.
