Figure 5From: Adherent cells avoid polarization gradients on periodically poled LiTaO3 ferroelectrics REF52YFP after 18Â h of seeding on periodically poled LiTaO 3 . Cell focal contacts imaged by fluorescence microscopy of cells YFP stained paxillin (a) and the phase contrast image (b). The cells did not show either oriented anisotropy in shape or preferential positioning of focal contacts with respect to the surface polarization domains.Back to article page
