Lymphocyte Surface Markers

Abstract

Great progress has been made in recent years toward a definition of the separate origin and separate function of different cell populations in lymphoid tissues.^{1 , 2} From these studies it has become clear that among the large, medium, and small lymphocytes of the peripheral blood, not one but several separable lymphocyte populations exist. For example, T-lymphocytes, B-lymphocytes, lymphocyte-like precursors of monocytes (M-cells), multipotential stem cells (S-cells) and committed stem cells of different cell lines (S₁, S₂, S₃, S₄) can be identified among the population of cells that are morphologically grouped as lymphocytes of . . .
