Article Title: Regulation of Granulocyte and Macrophage Populations of Murine Bone Marrow Cells by G-CSF and CD137 Protein
doi: 10.1371/journal.pone.0015565
Figure Lengend Snippet: 2×10 6 murine bone marrow cells at a density of 10 6 cells/ml were cultured for 7 days on plates that had been coated with 10 µg/ml of Fc or CD137-Fc protein. Where indicated, G-CSF was added daily at 10 ng/ml or other stated concentrations. The percentages of Gr-1 + cells (A) and CD14 + , F4/80 + cells (B), as well as absolute cell numbers (E), determined by flow cytometry on day 7, are depicted as means ± standard errors of 7 independent experiments. Dose responses of the combination of G-CSF and CD137 protein: Cells were treated with a fixed concentration of CD137-Fc at 10 µg/ml and varying the concentration of G-CSF at 0, 1, 10, or 100 ng/ml (C); or a fixed concentration of G-CSF at 10 ng/ml and varying the concentration of CD137-Fc at 0, 5, 10, or 20 µg/ml (D), and flow cytometry was performed for Gr-1, CD14 and F4/80 on day 7. These data are representative of two experiments with similar results. Statistical significance was determined by two tailed, paired Student's t-test. * p<0.05; ** p<0.01; n.s. not significant.
