MRD detection in flow cytometry (FCM)-purified HSPCs enriched from the BM of patients in CR after allo-HSCT precedes that in whole BM cells and more reliably predicts disease relapse. CMP, cytidine 5′-monophosphate; GMP, granulocyte monocyte progenitors; LMPP, lymphomyeloid primed progenitors; LT-HSC, long-term hematopoietic stem cells; MEP, megakaryocyte-erythroid progenitors; MPP, multipotent progenitors.
