Prolonged survival of granulocytes isolated from donors mobilized with G-CSF/dexamethasone. Granulocytes were isolated from healthy, control donors (□) and from the same donors treated with G-CSF and dexamethasone (■), and cultured for 20 hours in HBSS. Afterward, the cell viability was assessed by the use of annexin V/PI staining. Results represents data from 6 independent experiments (mean ± SD). *P < .05 (significant difference).
