Consistent with clustering of human bone marrow cells in CD45/SS gating (Figure 1A), bone marrow cells from healthy mice and mice without hematological malignancies showed similar distribution of cell populations (Figure 1B), except for the location of some B lymphocytes in the CD45dim cBG in most analyzed cases (n = 22) (Figures 1C and Supplementary Figure 1). This evidence concerns the gene PTPRC and hematologic disorder.
