Single-Cell Mass Cytometry of Acute Myeloid Leukemia and Leukemia Stem/Progenitor Cells.

Mass cytometry time-of-flight (CyTOF) empowers us to understand acute myeloid leukemia (AML) biology at the single-cell level. This technology, combined with advanced data-analysis methods, enables identification and characterization of the rare AML stem/progenitor cells that play key roles in drug resistance and AML relapse. Here we provide a protocol for AML sample preparation for CyTOF and keynotes emphasizing critical steps in and troubleshooting strategies for this procedure.
