Quality control in neutrophil granulocyte (PMN) concentrates by flow cytometry

Background: In peripheral blood, chemotaxis, phagocytosis, and oxidative burst of polymorphonuclear cells (PMNs) can be assessed by flow cytometry, whereas function tests, i.e., quality control in PMN concentrates designed for neutropenia therapy, are lacking.

Methods: PMN concentrates (n=6) harvested from healthy donors who had been premedicated with granulocyte colony-stimulating factor (G-CSF) and dexamethasone were stored undiluted (control, C; n=6) and diluted 1:4 (D; n=6) with autologous plasma for 72 h...
