CXCR 4 and SDF 1 expression in patients with MM. (A) Surface expression of CXCR 4 on plasma cells in the peripheral blood (PB) and bone marrow (BM) of patients with MM. Median percentage expression of CXCR 4 in plasma cells in the PB was 60% (range, 9%-96%) com. . . Yazan Alsayed et al. Blood 2007; 109: 2708 -2717 © 2007 by American Society of Hematology
