Figure 4From: Investigation of size–dependent cell adhesion on nanostructured interfaces Confocal images of focal adhesions formed on (a), (d), (g) the flat NOA 61 substrates, (b), (e), (h) 200 nm nanopillars and (c), (f), (i) 400 nm nanopillars for myoblast, CHO and MDCK cells, respectively. Green coloration indicates the location of vinculin proteins. Arrows indicate clustering of vinculin in the focal adhesions. Scale bar is 5 μm.Back to article page
