DNA methylation plays an important role in the self-renewal of hematopoietic stem cells and in the commitment to the lymphoid or myeloid lineages. Using purified CD34⁺ hematopoietic progenitor cells and differentiated myeloid cell populations from the same human samples, we obtained detailed methylation profiles at distinct stages of hematopoiesis. We identified a defined set of differentiation-related genes that are methylated in CD34⁺ hematopoietic progenitor cells but show pronounced DNA hypo  ...[more]
