| colony-stimulating factor | <cell biology> A glycoprotein growth factor that regulates the differentiation of particular cells. These substances act in either paracrine or autocrine fashion on marrow cells, appear to act synergistically and can exert actions on several lines of progenitor cells, and influence end cell function. These lymphokines induce the maturation and proliferation of white blood cells from the primitive cell types present in bone marrow such as the leucocyte, macrophage and monocyte lines. These substances can also be made by recombinant DNA technology for use clinically to speed bone marrow recovery typically following chemotherapy. Acronym: CSF (18 Jul 2002) |

| mother colony | A colony which gives rise to a secondary colony (a daughter colony), the latter growing on the surface of the former; the mother colony is larger than the daughter colony, and the characteristics of the colony's may differ. (05 Mar 2000) |
| mucoid colony | A colony showing viscous or sticky growth typical of an organism producing large quantities of a carbohydrate capsule. (05 Mar 2000) |
| multi-colony-stimulating factor | <cytokine> Product of mitogen activated T-cells: colony-stimulating factor for bone marrow stem cells and mast cells. A multilineage cell growth factor secreted by lymphocytes, epithelial cells, and astrocytes which stimulates clonal proliferation and differentiation of various types of blood and tissue cells. It is considered one of the haematopoietic colony-stimulating factors. Synonym: multi-CSF Acronym: IL-3 (12 Dec 1998) |
| multipotential colony-stimulating factor | <cytokine> Product of mitogen activated T-cells: colony-stimulating factor for bone marrow stem cells and mast cells. A multilineage cell growth factor secreted by lymphocytes, epithelial cells, and astrocytes which stimulates clonal proliferation and differentiation of various types of blood and tissue cells. It is considered one of the haematopoietic colony-stimulating factors. Synonym: multi-CSF Acronym: IL-3 (12 Dec 1998) |
| H colony | <cell culture> A colony of motile organisms forming a thin film of growth. Compare: O colony. Origin: Ger. Hauch, breath (05 Mar 2000) |
| smooth colony | A bacterial colony with a glistening, rounded surface; this type of colony is usually associated with increased virulence with respect to that of rough colony's. (05 Mar 2000) |
| spheroid colony | A colony of protozoa in which the individual cells are held together in a coherent spherical mass by a gelatinoid material. (05 Mar 2000) |
| daughter colony | A secondary colony growing on the surface of an older colony; it is smaller and may have characteristics different from those of the mother colony. (05 Mar 2000) |
| O colony | Growth of a nonmotile bacterium in discrete, compact colony's in contrast to a film of growth produced by some motile bacteria. Compare: H colony. Origin: Ger. Ohne Hauch, without breath (05 Mar 2000) |
| filamentous colony | In bacteriology, a colony composed of long, interwoven, irregularly disposed threads. (05 Mar 2000) |
| lenticular colony | A bacterial colony shaped like a lentil or a double-convex lens. (05 Mar 2000) |
| benign giant lymph node hyperplasia | Solitary masses of lymphoid tissue containing concentric perivascular aggregates of lymphocytes, occurring usually in the mediastinum or hilar region of young adults; similar changes have been reported outside the mediastinum and, if associated with interfollicular sheets of plasma cells, may progress to lymphoma or plasmacytoma. Synonym: angiofollicular mediastinal lymph node hyperplasia, Castleman's disease. (05 Mar 2000) |
| carcinoma, giant cell | An epithelial neoplasm characterised by unusually large anaplastic cells. It is highly malignant with fulminant clinical course, bizarre histologic appearance and poor prognosis. It is most common in the lung and thyroid. (12 Dec 1998) |
| malignant giant cell tumour | A type of bone tumour. (12 Dec 1998) |
