The complete methylome of hematopoietic stem cells and their immediate progeny

ABSTRACT: Hematopoietic stem cells (HSCs) constitute a rare cell population in bone-marrow and are capable of live-long self-renewal and production of all mature blood cell types. Cell differentiation processes are governed by epigenetic mechanisms whose study during early differentiation steps will provide insights into stem cell function and differentiation. We performed whole-genome bisulfite sequencing on HSCs and their immediate progeny, namely three different multipotent progenitor subpopulations (MPP1, MPP2, and MPP). Whole-genome bisulfite sequencing of hematopoietic stem cells (HSCs) and 3 different multipotent progenitor subpopulations (MPP). Three independent biological replicates each were analyzed.

In this study, we present integrated quantitative proteome, transcriptome, and methylome analyses of hematopoietic stem cells (HSCs) and four multipotent progenitor (MPP) populations. From the characterization of more than 6,000 proteins, 27,000 transcripts, and 15,000 differentially methylated regions (DMRs), we identified coordinated changes associated with early differentiation steps. DMRs show continuous gain or loss of methylation during differentiation, and the overall change in DNA methyl  ...[more]
