Enriching for human acute myeloid leukemia stem cells using reactive oxygen species-based cell sorting.

ABSTRACT

Isolation of leukemia stem cells presents a challenge due to the heterogeneity of the immunophenotypic markers commonly used to identify blood stem cells. Several studies have reported that relative levels of reactive oxygen species (ROS) can be used to enrich for stem cell populations, suggesting a potential alternative to surface antigen-based methods. Here, we describe a protocol to enrich for stem cells from human acute myeloid leukemia specimens using relative levels of ROS. This protocol provides consistent enrichment of leukemia stem cells. For complete details on the use and execution of this protocol, please refer to Lagadinou et al. (2013) and Pei et al. (2018).
