FACS analysis of circulating leukocytes showed that AMD3100 increased circulating inflammatory cells in both oil and CCl4 treated mice (A), with a specific increase in neutrophil populations (B). Additionally, isolated liver infiltrating inflammatory cells showed an increase in the total number of CD45-positive cells/gram of liver tissue (C) with a similar increase in the absolute number of neutrophils (D) in mice receiving AMD3100 both in oil and CCl4 treated mice. n=6-12, *P<0.05, **P<.01, ***P<.001.
