1 In this study, mobilization was induced with granulocyte colony-stimulating factor (G-CSF) in both C3-deficient (C3-/-) and C3a receptor-deficient (C3aR-/-) mice as well as in wild-type (wt) mice in the presence or absence of a C3aR antagonist, SB 290157. SB 290157 colony stimulating factor 3 (granulocyte) Mus musculus
2 The data indicated (1) significantly increased G-CSF-induced mobilization in C3-/- and C3aR-/- mice compared with wt mice, (2) significantly accelerated and enhanced G-CSF-induced mobilization in wt, but not in C3-/- or C3aR-/-, mice treated with SB 290157, and (3) deposition of C3b/iC3b fragments onto the viable bone marrow (BM) cells of G-CSF-treated animals. SB 290157 colony stimulating factor 3 (granulocyte) Mus musculus
