Patterning and spreading of HEKs on POEGMA-patterned substrates. A, Images of cell arrays (left, scale bar: 200 μm) and single cells (right, scale bar: 30 μm) spreading on 50 μm islands, 3 h after seeding (staining: red, F-actin, blue, DAPI); the substrates used were untreated glass (Glass), APTS-coated glass (APTS), LBL-coated glass with macro-initiator printing (Macro I) and gold (Gold). B, Projected cell areas (single cells only) measured from F-actin staining images (at least 100 cells for each substrate); mean ± SD; *P < 0.01.
