CD34 and acute myeloid leukemia: To define the cis-regulatory elements distinguishing CEBPAN/C from t(8;21) AML, we compared the open chromatin profiles (DNAse-Seq and ATAC-Seq data) of t(8;21) and CEBPAN/C and also compared both AML subtypes to normal CD34+ peripheral blood stem cells (PBSCs) (Fig.1B and Supplementary Fig. S1C).
