Survival of lethally irradiated C57BL/Ka mice receiving an intravenous injection of G-CSF–treated blood mononuclear cells separated on a discontinuous Percoll density gradient. In (A), hosts received 0.1 or 0.2 × 106 cells from the low-density fraction (MOB-Percoll-LDC), 2.5 or 10 × 106 cells from the 60% to 70% interface (MOB-Percoll-FR60), or 10 × 106 cells from the pellet at the bottom of the 70% Percoll solution (MOB-Percoll-FR70). In (B), hosts received 0.1 or 0.2 × 106 cells from the low-density fraction or 0.25 or 0.5 × 106 unfractionated cells. There were 10 to 12 mice in each group. Two experiments were combined.
