Figure 2. — Similar dose-dependent response after exposure of HAMs and monocyte-derived macrophages (MDMs) to FCB. Macrophage appearance varies by type of wood smoke particulate applied. (A) The percentage of cytoplasmic area occupied by PM by dose of FCB added in suspension to human macrophages. HAMs and MDMs show a similar dose dependency (n = 5 in each experiment). (B) The study design repeated to compare wood smoke from Norwegian birch trees with that obtained from Malawi mopane woodland. The dose-dependent response is maintained, but mopane wood produces a less opaque cytoplasmic appearance compared with birch. Error bars represent mean with 95% confidence interval (CI).
