The G-CSF–induced mobilization of peripheral blood progenitor cells is not enhanced in LFA-1 knock-out mice.

LFA-1 knock-out mice and their wild-type littermate controls were either treated with saline (n = 10 and n = 11, respectively) or with 5 μg G-CSF once daily for 5 days (n = 18 and n = 19, respectively). Twenty-four hours after the last injection, mice were killed and blood was obtained by cardiac puncture. Results are expressed as mean ± SD.
