Table 1. Quantitation of phagocytic activity following induction of macrophage phenotype.
Following treatments and phagocytosis assay (illustrated in Fig. 6, A and B) at least 500 cells were counted on each slide. The percentage of cells containing two or more phagocytized particles of opsonized zymosan was calculated and expressed as the mean ± S.D. (n=3).
