Traction stress of adherent HUVECs controlled by noncovalent anchorage of FN to polymer surfaces. (a) Traction stress map of an adherent cell on PEMA. Scale bar: 30 μm. (b) Mean maximum traction stress Tmax of HUVECs in dependence on polymer surface as determined from 3 to 6 independent experiments with each having 3–5 cells. Error bars indicate mean + SD.
