Hematopoietic stem cells with long-term repopulating activity can now be routinely obtained at purities of 40% to 50% from suspensions of adult mouse bone marrow. Here we describe robust protocols for both their isolation as CD45(+) EPCR(+) CD150(+) CD48(-) (ESLAM) cells using multiparameter cell sorting and for tracking their clonal growth and differentiation activity in irradiated mice transplanted with single ESLAM cells. The simplicity of these procedures makes them attractive for characterizing the molecular and biological properties of individual hematopoietic stem cells with unprecedented power and precision. © 2016 by John Wiley & Sons, Inc.
