| B-cell differentiation/growth factors | Various substances, usually obtained from the supernatant of T-cell cultures, such as interleukin 4, 5, and 6. These substances are necessary for B-cell growth, maturation, and differentiation into plasma cells or B memory cells. (05 Mar 2000) |

| biphasic growth curve | <cell culture, microbiology> A particular type of growth curve seen in cultured microorganisms in which they have two exponential growth stages separated by a plateau phase. This double-hump curve is produced when the microbes are cultured using two carbon sources, one of which must be used up before the second can be used. (19 Jan 1998) |
| bovine growth hormone | <endocrinology> A hormone secreted by the bovine pituitary gland. It is used to increase milk production by improving the feed efficiency in dairy cattle. (14 Nov 1997) |
| capon-comb-growth test | A test for androgenic activity, based upon the stimulation of comb growth in capons (castrated cockerels) or immature roosters. Synonym: capon-comb-growth test, cock's comb test. (05 Mar 2000) |
| radial growth phase | The early pattern of growth of cutaneous malignant melanoma, in which tumour cells spread laterally in the epidermis. (05 Mar 2000) |
| mammary derived growth inhibitor | Fatty acid binding protein that inhibits proliferation of mammary carcinoma cells. (18 Nov 1997) |
| vertical growth phase | Spread of melanoma cells from the epidermis into the dermis and later the subcutis, from which site metastasis may take place. (05 Mar 2000) |
| cell growth | <cell biology> Usually used to mean increase in the size of a population of cells though strictly should be reserved for an increase in cytoplasmic volume of an individual cell. (26 Mar 1998) |
| melanoma growth stimulatory activity | Cytokine of the C X C subfamily. Potent mitogen. Activates and is chemotactic for, neutrophils. (18 Nov 1997) |
| personal growth laboratory | A sensitivity training setting in which the primary emphasis is on each participant's potentialities for creativity, empathy, and leadership. See: sensitivity training group. (05 Mar 2000) |
| growth | 1. The process of growing; the gradual increase of an animal or a vegetable body; the development from a seed, germ, or root, to full size or maturity; increase in size, number, frequency, strength, etc.; augmentation; advancement; production; prevalence or influence; as, the growth of trade; the growth of power; the growth of intemperance. Idle weeds are fast in growth. 2. That which has grown or is growing; anything produced; product; consequence; effect; result. "Nature multiplies her fertile growth." (Milton) Origin: Icel. Gror, gri. See Grow. Source: Websters Dictionary (01 Mar 1998) |
| growth and embryonic development | Developmental processes from cell division to embryogenesis to postnatal growth and maturity. (12 Dec 1998) |
| growth arrest lines | Dense lines parallel to the growth plates of long bones on radiographs, representing temporary slowing or cessation of longitudinal growth. Synonym: Harris' lines. (05 Mar 2000) |
| growth associated proteins | <growth factor> Group of developmentally regulated polypeptides thought to be critical for the formation of neural circuitry. The acidic membrane phosphoprotein GAP 43 is synthesised and transported down regenerating and developing axons, pp46 localised in growth cone membranes during embryogenesis, B 50 in mature presynaptic membranes in the regulation of phosphotidylinositol turnover and F1 in the hippocampus during long-term potentiation, are now all known to be the same protein. (18 Nov 1997) |
| growth cone | <cell biology> A specialised region at the tip of a growing neurite that is responsible for sensing the local environment and moving toward the neuron's target cell. Growth cones are hand shaped, with several long filopodia that differentially adhere to surfaces in the embryo. Growth cones can be sensitive to several guidance cues, for example: surface adhesiveness, growth factors, neurotransmitters and electric fields (galvanotropism). (18 Nov 1997) |
