From: Particles induce apical plasma membrane enlargement in epithelial lung cell line depending on particle surface area dose

Figure 3

Surface area of the apical plasma membrane of A549 cells at different particle concentrations. * = p < 0.01 vs. negative control (NC). The mass of 3 × 107 1 μm particles and the surface area of 6 × 108 1 μm particles are approximately equal to the mass and surface area of 4.5 × 1011 0.05 μm particles, respectively. Increases in the surface area of the APM were observed at the same particle surface area concentration exposed to the cells. n = 5.
