In the left panel, cell monolayer was wounded at 0 h and, after 48 h, this scratch was closed under each condition (control, 20, 40, and 80 μg/cm2 of SPIONs). In the right panel, confluence measured with Incucyte® revealed that cell migration was not significantly affected by treatment with different concentrations of SPIONs (as indicated). p > 0.05Back to article page
