Representative images of endothelial cells and fibroblasts 12 h post DC stimulation (50 mV/mm). Both the electrically stimulated endothelial cells (A, C) and fibroblasts (B, D) appeared morphologically similar to unstimulated paired controls. Samples were fixed and stained with phalloidin for actin (red) cytoskeleton and DAPI for nuclei (blue). Images were taken at 20×, bar=100 μm, direction of electric field is shown.
