title: B-lymphocyte subpopulations.
abstract: B lymphocytes are exceptionally diverse, partly because different clones have membrane receptors with specificities for different antigens and partly because the cells exist in a series of distinct differentiation states and may constitute more than a single cellular lineage. In this article John Kung and William Pail discuss heterogeneity with particular reference to the subpopulations of immunoglobidin-bearing B lymphocytes and their distinctive properties.
