There is a statistically significant difference in the expression of IL7R, CCR7, KLRB1, SELL, and PTPRC in AML bone marrow and normal human bone marrow, and the lowest expression value in AML is almost higher than the highest value in the normal group, and this expression difference is more pronounced in AML than in other tumors (Fig. 4B–F). This evidence concerns the gene CCR7 and acute myeloid leukemia.
