Cover picture: Fluorescence ratio images of focal adhesion (FA) proteins in REF52 cells cultured for 3 h (first and second columns) and 24 h (third and fourth columns) on 58 nm (first and third columns) and 108 nm (second and fourth columns) RGD nanopatterns. The rows present the images with paxillin in red, zyxin in blue, and actin in green. The last row shows the ratio between paxillin and zyxin intensities. The prominence of zyxin in FA formed with the 108 nm surface is considerably lower than that measured in FA formed with the 58 nm surface. See the article by Cavalcanti-Adam et al. on page 2964.
