Fig. (4) FOXP1 relative mRNA expression in (A) total bone marrow aspirates and (B) purified CD138+ plasma cells. MM = multiple myeloma at diagnosis; MM-R = MM patients at relapse; MM-T, refers to samples taken from patients post-treatment; SM = smoldering myeloma; P = plasmacytoma; WM = Waldenstroms Macroglobulinaemia; AL = amyloid; R = reactive marrow; NHL= non-Hodgkin's lymphoma; no MM, includes a heterogenous group of patients whose plasma cells should not be malignant or pre-malignant. * These patients did not fall into one of the above categories. Bone marrow trephines from cases 7 and 8 were reported as LPL or myeloma, clinically the diagnosis was LPL; case 9 had a bone plasmacytoma, the bone marrow aspirate was not reported to show increased plasma cells and the trephine was inadequate.
