2D magnetic guidance of VFF. a Magnetic guidance of SPION-loaded VFF shows cells only growing in areas where the magnet is present. Upper: VFF loaded with 0 (control), 20, or 40 μg/cm² SPIONs seeded in a 6-well plate, which was placed on top of a 24-well magnet plate (lower). (b) Crystal violet (upper) and Prussian blue (lower) staining of VFF grown over the magnet (left) and in magnet-free zone (right). Quantitative analysis: % of cells measured in 4 mm distance of the magnet
