The PI for nonopsonized RBCs, based on the mean of 3 experiments, was 0 and 1 for cells not exposed to piceatannol, respectively not stimulated and stimulated with G-CSF (300 ng/mL); and 0 and 0 both for unstimulated and G-CSF—stimulated cells, both in the presence of 25 μg/mL or 50 μg/mL piceatannol.
