a (Left) Typical example of chiral organisation of the actin cytoskeleton (magenta) in a single fibroblast-type cell plated on a circular fibronectin island (48 μm diameter). Actin was labelled with phalloidin, and the nucleus with Hoechst-33342 (green). (Right) Phase-contrast image of a multicellular chiral alignment pattern resembling the Cyrillic letter И on a rectangular fibronectin island (600 × 300 µm ) 48 h after seeding. Scale bars, 10 μm (left), 100 μm (right). b Time-lapse imaging of a LifeAct-transfected cell (magenta) interacting with the boundary of the rectangular fibronectin (FN; white) island (Cell 1; dashed semicircular outline). Only selected regions of the rectangular island were visualised by high-magnification live-cell imaging; time points (hh:mm) started 30 min after seeding.

Article Snippet: To visualise actin cytoskeleton in cells during live imaging, cells were either transfected with LifeAct-GFP DNA plasmid via electroporation (Neon transfection system, Life Technologies) following the manufacturer’s instructions, or labelled using SPY650-FastAct (Cytoskeleton Inc., catalogue no. CY-SC505).
