Mobilization of hematopoietic progenitors by G-CSF treatment.

<p>WT or Robo4-mutant mice were treated with G-CSF for 5days. BM and peripheral blood (PB) were harvested at 6 hours after the last dose of G-CSF, and the numbers of CFU-GM per 1×10⁵ BM or PB cells were assessed by colony assays. Data are mean +/− S.D. (n = 6). *p<0.05.
