Fluorescence detection of F-actin in BCAECs cultured on the experimental materials for 1 and 3Â days. a NTs showing a well spread cellular morphology with the evident presence of cytoskeleton stress fiber at day 1 of culture; b Ti6Al4V control surface at day 1 illustrating an aligned cellular growth but with a lower cellular spreading; c NTs at day 3 displaying the presence of well-defined actin stress fibers; and (d) Ti6Al4V control surface showing an altered cellular morphology with the absence of stress fibers
