bDLE increases the phagocytic capacity of K562 cells. (A) Untreated cells, (B) 0.07 U/ml bDLE, (C) 0.14 U/ml bDLE, (D) 0.21 U/ml bDLE, (E) 0.28 U/ml bDLE, (F) 0.35 U/ml bDLE, (G) 10 ng/ml phorbol myristate acetate or (H) dimethyl sulfoxide (1.5%, v:v) were incubated for 96 h. Cells were collected and FITC-Dextran was added and incubated for 1 h at 37°C. Flow cytometry data show representative results from one of three independent experiments. FITC, fluorescein isothiocyanate; bDLE, bovine dialyzable leukocyte extract.
