| exponential growth | <biology> A rate of growth of an organism, a part of an organism, or a population of organisms which, when graphed, produces an exponential or logarithmic curve. Such a rate occurs, for example: during the exponential growth phase, when a population of bacterial (or other) cells divide at a constant rate so that the total number of cells doubles with each division.

| keratinocyte growth factor | <growth factor> A growth factor structurally related to fibroblast growth factor. (18 Nov 1997) |
| urban growth boundary | A land use boundary surrounding a city. Urban land uses are permitted within the urban growth boundary. (05 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, 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.

| 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) |
| foetal growth retardation | The failure of a foetus to maintain its expected growth potential at any gestational stage. (12 Dec 1998) |
