| cluster of differentiation 4 | A glycoprotein found on various subsets of T-cells, i.e., usually no helper and some T cytotoxic cells. (05 Mar 2000) |
|---|---|
| cluster of differentiation 8 | Membrane glycoprotein found on subsets of T lymphocytes. CD8 is expressed on T cytotoxic cells and T suppressor cells. Acronym: CD (05 Mar 2000) |
| correlative differentiation | Differentiation due to the interaction of different parts of an organism. (05 Mar 2000) |
| self-differentiation | Differentiation resulting from the action of intrinsic causes. (05 Mar 2000) |
| sex differentiation | Differentiation of male and female tissues and organs during embryogenesis, but after sex determination (sex determination (genetic)). (12 Dec 1998) |
| sex differentiation disorders | Disorders in the differentiation process of gonadal tissues and organs during embryogenesis. (12 Dec 1998) |
| neuronal differentiation | Acquisition during development of specific biochemical, physiological and morphological properties by nerve cells. (18 Nov 1997) |
| differentiation | The distinguishing of one thing or disease from another. (18 Nov 1997) |
| differentiation antigen | Any large structural macromolecule that can be detected by immune reagents and that also is associated with the differentiation of a particular cell type or types. Many cells can be identified by their possession of a unique set of differentiation antigens. There should be no implication that the antigens cause differentiation. (18 Nov 1997) |
| invisible differentiation | Differentiation of the cellular chemical constituents in the embryo prior to cytodifferentiation; sometimes recognizable histochemically. Synonym: invisible differentiation. (05 Mar 2000) |
| echocardiographic differentiation | The processing of a signal so that the output depends upon the rate of change of the input; e.g., it will display changes in amplitude but will reduce the duration of the waveform. (05 Mar 2000) |
| age factors | Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from aging, a physiological process, and time factors which refers only to the passage of time. (12 Dec 1998) |
| bacteriocin factors | Bacterial plasmid's responsible for the elaboration of bacteriocins. Synonym: bacteriocin factors, bacteriocinogens. (05 Mar 2000) |
| biological factors | Compounds made by living organisms. They have biological or physiological activities. (12 Dec 1998) |
| biotic factors | Environmental factor's or influences resulting from the activities of living organisms, as contrasted to those resulting from climatic, geological, or other factor's. (05 Mar 2000) |
