Tracking epigenetic changes during human leukemogenesis

We have developed a human model leukemia system where healthy cord blood (CB) cells from single donors are used to generate dozens of human leukemias driven by KMT2A fusions. These models have been used for the study of the stepwise changes in donor CB cells as they undergo leukemic transformation driven by the KMT2A-MLLT3 (KM3) fusion gene. We specifically studied the epigenetic changes that occur in this specific AML subgroup through ChIP-seq of histone modifications and ATAC-seq and DNA methylation through Methyl-Seq. The overall design is to study epigenetic changes in human Hematopoietic Stem and Progenitor Cells (HSPCs) during leukemogenesis
