  • Patent number: 5898066
    Abstract: Cell culture conditions were developed which maintain the nerve cells of the retina in well-defined, serum-free conditions. The molecular factors that stimulate axonal regeneration from these neurons were characterized. The glial sheath cells that surround the axons of the optic nerve release two molecules that trigger and sustain nerve regeneration. One of the molecules is referred to as axogenesis factor 1 (AF-1), and is a low molecular weight polypeptide with a size in the range of 1000 daltons. The second molecule, AF-2, is a larger protein with a size of approximately 12,000 daltons. Studies indicate that these factors are strongly involved in CNS regeneration, and are therefore useful in the treatment of spinal cord and other nervous tissue damage.

  • Patent number: 5712380
    Abstract: The vascular endothelial cell growth factor (VEGF) inhibitors of the present invention are naturally occurring or recombinantly engineered soluble forms with or without a C-terminal transmembrane region of the receptor for VEGF, a very selective growth factor for endothelial cells.

  • Patent number: 5668104
    Abstract: An 18 kDa protein, denominated FDF-3, has been isolated from cultures of human fibroblasts and has been found to potentiate the growth- and differentiation-promoting activities of certain cytokines toward hematopoietic progenitor cells. The amino acid sequence of the FDF-3 protein, shown in SEQ ID NO: 14, corresponds to the sequence of a C-terminal domain of human fibronectin. The protein is useful in combination with IL-3, G-CSF, GM-CSF, or SCF (stem cell factor) in the expansion of hematopoietic cell populations in vitro or in therapeutic methods to promote recovery from leukopenia or myelosuppresion in vivo.
