Myeloid lineage analysis of bone marrow cells. Bone marrow cells were isolated from wild-type (WT; n = 4) and C/EBPβ-deficient (KO; n = 4) adult mice, stained with fluorescent-labeled antibodies against myeloid lineage-specific antigens (Mac1/CD11b, CD14, and Gr-1), and analyzed by flow cytometry. Results represent the mean plus or minus SD of 4 mice in each cohort.
