The image shows a fluorescence microscopy image of mouse mammary adenocarcinoma cells grown on polyimide with a patterned surface, as presented by Denise Langheinrich, Edith Yslas, Martín Broglia, Viviana Rivarola, Diego Acevedo, and Andrés Lasagni on page 415. The cells are highly aligned to the direction of the line-like pattern (spatial period: 1 μm), which was fabricated by using direct laser interference patterning technology. This flexible and rapid method offers the possibility of providing polymer and other surfaces with a variety of perfectly controlled periodic patterns by direct laser ablation.
