Single Stem Cell Lineage Analysis of the Leukemic Clones Responsible for Acute Myeloid Leukemia Relapse Based on the Functional and Genomic Properties at Diagnosis

Single cell lineage analysis was used to assess clonal genetic heterogeneity and functional aspects of AML HSPCs derived at diagnosis and relapse. To address inherent limitations of single cell analysis, we developed a unique high-resolution technique capable of following single cell-derived subclones of different HSPC subpopulations during the AML course. Each of these subclones was evaluated for chemo-resistance, in-vivo leukemogenic potential in Nod Scid Gamma (NSG) mice, mutational profile, and the subclone cell of origin identified using retrospective cell lineage reconstruction.
