Expression of granulocyte and monocyte/macrophage genes by myeloid cells. (A) Quantitative RT-PCR from the indicated cell populations, normalized to ActinB and expressed relative to control CD11bhi Gr1locells for the following (A) neutrophil genes: myeloperoxidase (MPO), neutrophil elastase (ELANE), lactoferrin (LF), neutrophil collagenase (NC), and neutrophil gelatinase (NG), and (B) monocyte genes: calpactin (Cal), cathepsin B (CaB), fibronectin 1 (FN1), Legumain (LEG), and phospholipid transfer protein (PTP). Experiments were performed 3 times each on 3 different biologic specimens. *P < .05 between KO and control CD11bhi Gr1lo cells; **P < .05 between KO and control CD11bhi Gr1hi cells.
