| Abstract: |
Dendritic cells (DCs) are a heterogenous population of professional antigen-presenting cells that play an “educator” role in immunity. Multiple DC subsets collaboratively initiate and orchestrate innate and adaptive immune responses. Recent advances in our ability to investigate cellular transcription, signaling, and function at the single-cell level have opened opportunities to examine heterogeneous populations at unprecedented resolutions. Culturing of mouse DC subsets from single bone marrow hematopoietic progenitor cells, that is, clonal analysis, has enabled identification of multiple progenitors with distinct potentials and furthered understanding of mouse DC development. However, studies of human DC development have been hampered by the lack of a corresponding system to generate multiple human DC subsets. Here, we describe a protocol to functionally profile the differentiation potentials of single human hematopoietic stem and progenitor cells (HSPCs) to multiple DC subsets, myeloid and lymphoid cells that will facilitate investigation of human DC lineage specification and reveal its molecular bases. © 2023, The Author(s), under exclusive license to Springer Science+Business Media, LLC, part of Springer Nature. |
