Figure 4

IL-8 response of in vitro cell cultures treated with equal mass concentrations (53 μg/cm2) of nano- and micron-sized particles of the same nominal substance. A. BEAS-2B cells in LHC-9 media with 0.1% BSA, B. NHBE cells in BEGM media with 0.1% BSA. IL-8 in pg/mL, mean ± s.d., N = 9, * denotes statistically greater than control. Treatment codes are in Table 1.
