Figure 4From: Control of growth and inflammatory response of macrophages and foam cells with nanotopographyImmunostaining showing distribution of vinculin (green) and actin filaments (red) in macrophages and foam cells. Macrophages and foam cells were seeded on flat, 10-, 50-, 100-, and 200-nm nanodot arrays for 3 days, and their morphology was observed by confocal microscopy. Scale bar = 25 μm.Back to article page
