We collected available DNase I footprint datasets in six different human cell-types from three healthy donors (CD34+ (mobilized), CD20+ and Th1 cells), transformed B-lymphocytes (GM12865) and two cancer cell-types where c-Myb is upregulated: erythroleukaemia (K562) and promyelocytic leukaemia (NB4) [31]. This evidence concerns the gene CD34 and acute promyelocytic leukemia.
