Image (IMAGE) National University of Singapore Caption Image of fibroblast cells grown on artificial nanofibres with differential patterning and spacing. When the nanofibres were closely spaced (left panel), cells easily form stable focal adhesions (seen as bright green dots along the cell boundary) leading to increased cell spreading and migration. On the other hand, when the spacing between the nanofibres was increased, (right panel), cells have trouble forming strong focal adhesions and subsequently spread to a lesser extent.
