2 (in cell biology) a mass of cells in a culture or in certain experimental tissues, such as a spleen colony.

colony

A local growth of large numbers of micro-organisms derived from one individual (a clone) or from a small number. A visible growth of bacteria or other microorganisms on a nutrient medium in a culture plate.

colony

  1. an aggregated group of separate organisms such as birds, which have come together for a specific purpose such as breeding.
  2. a group of incompletely separated individuals organised in associations, as in some hydrozoan COELENTRATES and polyzoans.
  3. a localized population of microorganisms, e.g. bacteria, derived from a single cell grown in culture.

colony

a discrete group of organisms, as a single cluster of bacteria in a culture that was produced from a single starting bacterium.

colony-forming units
colonies of pluripotent stem cells located and quantified in the spleen. Colonies grown in vitro interact with erythropoietin to give rise to morphologically identifiable erythroid cells.
colony-stimulating factors
cytokines produced by lymphocytes and mononuclear phagocytes which stimulate the growth and differentiation of hematopoietic cells. Includes granulocyte-macrophage colony-stimulating factor, monocyte-macrophage colony-stimulating factor and granulocyte colony-stimulating factor.
