Basic Fibroblast Growth Factor (FGF) is substantially purified by the employment of affinity chromatography using heparin-linked support material. Described is a simplified three step procedure for extracting basic FGF from either mammalian brain or mammalian pituitary tissue. Salt precipitation, e.g., with ammonium sulfate is used to provide a partially purified precipitate that is then subjected to ion-exchange chromatography, e.g., using a Carboxymethyl-Sephadex column. Substantially pure bas…

Disclosed is a human Fibroblast growth factor-13 polypeptide and DNA(RNA) encoding such polypeptide. Also provided is a procedure for producing such polypeptide by recombinant techniques. Also disclosed are methods for utilizing such polypeptide for promoting wound healing for example as a result of burns and ulcers, to prevent neuronal damage associated with stroke and due to neuronal disorders and promote neuronal growth, and to prevent skin aging and hair loss, to stimulate angiogenesis, meso…

The present invention provides for numerous cell factors involved in a novel cellular pathway that is activated in response to ionizing radiation. Several cell factor activities are described which either complement the radioresistant DNA synthesis phenotype of Ataxia Telangiectasia cells, or inhibit DNA synthesis in the cell. Other cell factor activities are described which inhibit mitosis by arresting the cell cycle prior to cell division. It is contemplated that compositions comprising the su…

Disclosed is a human Fibroblast growth factor-11 polypeptide and DNA(RNA) encoding such polypeptide. Also provided is a procedure for producing such polypeptide by recombinant techniques. Also disclosed are methods for utilizing such polypeptide for promoting wound healing for example as a result of burns and ulcers, to prevent neuronal damage associated with stroke and due to neuronal disorders and promote neuronal growth, and to prevent skin aging and hair loss, to stimulate angiogenesis, meso…

A fibroblast growth factor (FGF) receptor including a basic fibroblast growth factor receptor has been purified. Various forms have been identified including soluble forms lacking any transmembrane segment. DNA sequences encoding full-length fibroblast growth factor receptors and polypeptides comprising a portion of an FGF-R ligand-binding domain have been isolated and sequenced. These DNAs include DNAs encoding for a basic FGF-R and a human FGF-R and are operably linked to control sequences and…

The present invention relates to a novel FGF-13 protein which is a member of the fibroblast growth factor (FGF) family. In particular, isolated nucleic acid molecules are provided encoding the human FGF-13 protein. FGF-13 polypeptides are also provided as are vectors, host cells and recombinant methods for producing the same. The invention further relates to screening methods for identifying agonists and antagonists of FGF-13 activity. Also provided are diagnostic methods for detecting FGF-13-re…

Substantially pure bovine pituitary fibroblast growth factor, a 146 amino acid residue polypeptide, is produced. The amino acid residue sequence of bpFGF is disclosed as well as a DNA chain encoding the polypeptide. By appropriately inserting a synthesized DNA chain into a cloning vector and using the cloning vector to transform cells, synthetic bpFGF can be obtained from transformed cell lines, both prokaryotic and eukaryotic.

Antagonists to basic fibroblast growth factor, a 146 amino acid residue polypeptide, are produced. These antagonists are generally between 4 and 45 residues in length and are characterized by their ability to interact with the FGF receptor and/or inhibit and therefore modulate endothelial and other cell growth. One group of these antagonists includes the four residue sequence which forms basic FGF(36-39), namely Pro-Asp-Gly-Arg. Another of these antagonists includes the sequence of bovine basic …
