abstract：:HL-60 cells are promyelocytic leukemia cells that respond to culture conditions with differentiation into granulocytelike or macrophagelike phagocytes. O2 metabolism is critical to the microbicidal function of phagocytic cells. O2 metabolism was studied in HL-60 cells differentiated with dimethylsulfoxide (Me2SO) and ...
