“…We also demonstrated that the expression-pattern of CD229 on PC was homogenous in the majority of samples with a median CV of immunofluorescence of only 66.3 compared with 97.3 for CD138. CD38 is reportedly expressed on 100% PC (26,27) and we found that CD38 was positive on 100% PC in all samples except two. In this study, we assessed CD229 expression on non-PC in 20 additional BM samples and found similarly, that CD229 is also expressed, to a lesser extent, on dendritic cells, basophils, T-cells and mature B cells (Supporting Information Figure S1).…”
