We first incubated cells with PE-conjugated anti-mouse antibodies directed against CD11b (clone M1/70), CD19 (clone 6D5), CD90.2 (clone 53-2.1), CD11c (clone N418), CD4 (clone GK1.5), CD8a (clone 53-6.7), CD127 (clone A7R34), CD49b (clone DX5), Ly-6G (clone 1A8), Ly-6C (clone HK1.4), TER-119 (clone TER-119) (all BioLegend). Then cells were stained with antibodies directed against c-kit (BioLegend, clone 2B8), sca-1 (BioLegend, clone D7), CD34 (BD Bioscience, clone RAM34), CD16/32 (BioLegend, clone 93), CD115 (eBioscience, clone AFS98). The term LSK refers to hematopoietic stem and progenitor cells based on their characteristic surface expression pattern (Lineage neg, Sca-1+, c-Kit+) [42 (link)], specified as Lin (CD11b, CD19, CD90.2, CD11c, CD4, CD8a, CD127, CD49b, Ly-6G, Ly-6C, TER-119) low, sca-1 high, c-kit high and was used throughout the manuscript as it best describes the cell population investigated. Granulocyte–macrophage precursors (GMP) were defined as Lin (CD11b, CD19, CD90.2, CD11c, CD4, CD8a, CD127, CD49b, Ly-6G, Ly-6C, TER-119) low, c-kit high, sca-1 low, (CD34/CD16/32) high, CD115 int/low. Monocyte-dendritic cell precursor (MDP) were defined as Lin (CD11b, CD19, CD90.2, CD11c, CD4, CD8a, CD127, CD49b, Ly-6G, Ly-6C, TER-119) low, c-kit int/high, sca-1 low, (CD34/CD16/32) high, CD115 high [25 (link)].
