The ‘cluster of differentiation’ antigens that were originally marker antigens found on different classes of lymphocytes using monoclonal antibodies. The CD nomenclature was introduced as a means of bringing consistency because the same CD antigen can be recognized by different monoclonal antibodies; international workshops are run to cross-compare antibodies against standard antigens. The CD antigens are no longer restricted to the immune system and the list covers a wide range of cell surface antigens, some of which are transiently expressed at particular stages of differentiation or following stimulation of cells by particular agents. In mid-2009 the list extended to CD350.
