Field-dependent fibroblast orientation on charged surfaces is independent of polarity and adsorbed serum proteins.


Electrets were used to induce a dipolar charge on fluorinated ethylene propylene (FEP) and bacteriological grade polystyrene (PS) films. The serum protein surface concentration adsorbed on FEP and PS from cell-free media was dependent on both the magnitude and the polarity of the surface charge density. Chick embryo fibroblasts were cultured on charged and… (More)
