| fibroblast growth factor, basic | A single-chain polypeptide of approximately 15-16 kD which has been isolated from a variety of cells. It has a 55% amino acid residue identity to acidic fibroblast growth factor and has potent heparin-binding activity. However, in contrast to the acidic fibroblast growth factor, heparin does not potentiate the biological activities of bfgf. The growth factor is an extremely potent inducer of DNA synthesis in a variety of normal diploid mammalian cell types from mesoderm and neuroectoderm lineages and promotes cellular differentiation in vitro. (12 Dec 1998) |

| receptors, fibroblast growth factor | Specific molecular sites or structures on cell membranes that react with fibroblast growth factors (both the basic and acidic forms), their analogs, or their antagonists to elicit or to inhibit the specific response of the cell to these factors. These receptors frequently possess tyrosine kinase activity. (12 Dec 1998) |

| fibroblast growth factor | <growth factor> Acidic fibroblast growth factor (alpha FGF, HBGF 1) and basic FGF (beta FGF, HBGF 2) are the two founder members of a family of structurally related growth factors for mesodermal or neuroectodermal cells. Synonym: heparin binding growth factor. Acronym: FGF (18 Nov 1997) |
| fibroblast growth factor, acidic | <chemical> A growth factor which has been isolated from a variety of cells. It contains 154 amino acid residues and has potent heparin-binding activity. Heparin potentiates the biological activities of afgf. The growth factor is an extremely potent inducer of DNA synthesis in a variety of normal diploid mammalian cell types from mesoderm and neuroectoderm lineages and also has chemotactic and mitogenic activities. Chemical name: Fibroblast growth factor (human brain acidic protein moiety reduced) (12 Dec 1998) |
| fibroblast growth factor receptor | Family of receptor tyrosine kinases for fibroblast growth factor. (18 Nov 1997) |
| fibroblast growth factor receptor-like embryonic kinase | <enzyme> Found in avian embryonic tissue; involved in early differentiation of skeletal muscle. Registry number: EC 2.7.1.- Synonym: frek (26 Jun 1999) |
| chick heart fibroblast | <cell culture> The cells that emigrate from an explant of embryonic chick heart maintained in culture. Often used as archetypal normal cell. (05 Jan 1998) |
| fibroblast | <pathology> Resident cell of connective tissue, mesodermally derived, that secretes fibrillar procollagen, fibronectin and collagenase. (18 Nov 1997) |
| fibroblast interferon | <cytokine> One of the type I interferons produced by fibroblasts in response to stimulation by live or inactivated virus or by double-stranded RNA. It is a cytokine with antiviral, antiproliferative, and immunomodulating activity. Synonym: fibroblast interferon. Pharmacological action: adjuvants, immunologic, antineoplastic agent, antiviral agents. Chemical name: Interferon-alphaB (human leukocyte protein moiety reduced) (12 Dec 1998) |
| brain-derived growth factor | <growth factor> Small basic protein purified from pig brain, a member of the family of neurotrophic factors that also includes Nerve Growth Factor and neurotrophin 3. In contrast to nerve growth factor, brain-derived neurotrophic factor is predominanantly (though not exclusively) localised in the CNS. It supports the survival of primary sensory neurons originating from the neural crest and ectodermal placodes that are not responsive to NGF. In the brain brain-derived neurotrophic factor has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons. Acronym: BDGF (12 Dec 1998) |
| vascular endothelial growth factor | A growth factor that is responsible for the growth of blood vessels. (12 Dec 1998) |
| receptors, epidermal growth factor-urogastrone | Glycoproteins of about 170 kD that have protein kinase activity and span the plasma membranes of growing cells, including tumours. They are activated by the binding of epidermal growth factor-urogastrone which then initiates DNA and protein synthesis. They are not found on mitotically quiescent cells except in the stomach where they control the synthesis and release of digestive enzymes and gastric acid. Transforming growth factor alpha also binds to and activates these receptors. (12 Dec 1998) |
| receptors, growth factor | Cell surface receptors that bind growth or trophic factors with high affinity, triggering intracellular responses which influence the growth, differentiation, or survival of cells. (12 Dec 1998) |
| receptors, insulin-like-growth factor I | Specific proteins on or in cells to which insulin-like growth factor I (somatomedin c) binds and thereby modifies the function of the cells. These receptors contain transmembrane and cytosolic domains, bind igf-I preferentially, and have high-affinity sites for igf-II. The alpha-subunit has a mw of 130 kD and the beta subunit possesses tyrosine kinase activity. (12 Dec 1998) |
| receptors, insulin-like-growth-factor II | Specific proteins on or in cells to which insulin-like growth factor II and mannose-6-phosphate bind and thereby modify the function of the cells. These receptors have a mw of 250 kD and possess no tyrosine kinase activity. (12 Dec 1998) |
| receptors, nerve growth factor | Cell surface receptors that bind nerve growth factor (ngf) and trigger intracellular changes influencing the behaviour of cells. Nerve growth factor receptors mediate the effects of nerve growth factor on the survival and growth of neurons. (12 Dec 1998) |
