Figure 3

Representative flow cytometric histograms of bone marrow aspirate. (a) There is a CD45-dim population of abnormal cells with low-side scatter (painted red), comprising about 15% of total cells. (b) The cells of interest are negative for CD38 and CD138. (c) These cells are negative for CD19, but partially positive for CD79b, with a subset moderately positive for CD79b (painted blue). (d) These cells are positive for CD71 and negative for cytoplasmic MPO.
