CD66b+CD33dimHLA-DR− cells within PBMCs from lymphoma patients at diagnosis displayed a wide variability with respect to the side scatter parameter (SSC) by flow cytometric analysis (Figure 1, left panel column), as well as morphological features consistent with a population of granulocytic cells in different stages of maturation (Supplementary Figure 2). This evidence concerns the gene CEACAM8 and lymphoma.
