In vitro clonal multilineage differentiation of distinct murine hematopoietic progenitor populations

Here we describe an in vitro co-culture system that can differentiate hematopoietic progenitor populations to all major hematopoietic lineages at clonal level. We present both a sensitive single-cell switch-culture system as well as a less laborious alternative barcoding protocol more convenient for larger cell numbers. Importantly, generation of all lineages from single long-term hematopoietic stem cells are described, following 21 days of culture. This protocol represents an efficient tool for validation experiments for single-cell genomics data. For complete details on the use and execution of this protocol, please refer to Safi et al. (2022).(1)
