The field of chemokine biology is a rapidly advancing one, with over 50 chemokines identified that mediate their effects through one or more of 16 different chemokine receptors. Chemokines, originally identified as chemotactic cytokines, manifest a number of functions, including modulation of blood cell production at the level of hematopoietic stem/progenitor cells and the directed movement of these early blood cells. This report reviews chemokines and chemokine/receptor activities mainly in the context of hematopoietic cell regulation and the numerous chemokines that manifest suppressive activity on proliferation of stem/progenitor cells. This is contrasted with the specificity of only a few chemokines for the chemotaxis of these early cells. The large number of chemokines with suppressive activity is hypothesized to reflect the different cell, tissue, and organ sites of production of these chemokines and the need to control stem/progenitor cell proliferation in different organ sites throughout the body.
