Cytometric bead array analyses of (a) IL-6 or (b) TNFα secreted from RAW246.7 exposed to asbestos (35 μg/cm2) for 48 h. n = 3 wells; experiments were repeated three times; error bars = SEM; *Exposure to asbestos significantly increased RAW264.7 macrophage secretion of IL-6 and TNFa compared to that by the No Treatment (0 μg/cm2) group; p < 0.05.
