  • Publication number: 20060025577
    Abstract: A novel growth factor specific for vascular endothelial cells has been identified in conditioned medium of bovine pituitary derived folliculo stellate cells. This factor, named folliculo stellate derived growth facto (FSdGF) or vascular endothelial growth factor (VEGF), was purified to homogeneity by a combination of heparin sepharose affinity chromatography, Bio Gel P-60 exclusion chromatography, Mono S ion exchange chromatography and hydrophobic chromatography on a C4 reverse phase HPLC column. The factor is also found in the murine AtT-20 cell line. Alternatively, the growth factor is purified by a first reverse phase HPLC using acetonitrile gradient followed by a second reverse phase HPLC using an isopropanol gradient. FSdGF, having a molecular weight of about 43,000 da, was characterized as a glycoprotein composed of two homologous sub units with MW of about 23 kDa. FSdGF was a potent mitogen for vascular endothelial cells with activity detectable at 10 pg/ml and saturation at 500 pg/ml.

  • Publication number: 20050090445
    Abstract: The present invention relates to a keratinocyte growth factor fragment, KGFdes1-23, or an analog thereof that is composed of a portion of an amino acid sequence of mature, full length keratinocyte growth factor, KGF163. The fragment exhibits at least a 2-fold increase in mitogenic activity as compared to a mature, recombinant keratinocyte growth factor, rKGF, but lacks a sequence comprising the first 23 amino acid residues, C-N-D-M-T-P-E-Q-M-A-T-N-V-N-C-S-S-P-E-R-H-T-R- (SEQ ID NO: 2) of the KGF163 N-terminus. The present invention also relates to a DNA molecule encoding KGFdes1-23, an expression vector and a transformed host containing the DNA molecule, and a method of producing KGFdes1-23 by culturing the transformed host. The present invention further relates to a conjugate of KGFdes1-23 and a toxin molecule, and the use thereof for treatment of hyperproliferative disease of the epidernis.

  • Publication number: 20020103155
    Abstract: A method is described for introducing an FGF-5 nucleic acid sequence into a mammalian host cell. The FGF-5 nucleic acid sequence lacks the signal sequence so that cells that are transformed with the sequence will not become tumirogenic. It is intended that the FGF-5 sequence is introduced into mammalian cells to promote angiogenesis. Preferably, the FGF-5 sequence is introduced into a human patient to treat myocardial ischemia or peripheral vascular disease.

  • Patent number: 5464774
    Abstract: Substantially pure mammalian basic fibroblast growth factors are produced. The amino acid residue sequences of bovine and human bFGF are disclosed as well as a DNA chain encoding the polypeptide of the bovine species. By appropriately inserting a synthesized DNA chain into a cloning vector and using the cloning vector to transform cells, synthetic bovin bFGF can be obtained from transformed cell lines, both prokaryotic and eukaryotic.

  • Patent number: 4902782
    Abstract: 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 basic FGF fractions are then obtained by fractionating the further partially purified fractions using affinity chromatography on a heparin-linked support e.g., Heparin-Sepharose.
