A–C Gross appearance of SF, SF/ASC–ECM, and SF/ASC–ECM–Fe3O4 NP–VEGF scaffolds. D–F Low-magnification SEM images of SF, SF/ASC–ECM, and SF/ASC–ECM–Fe3O4 NP–VEGF scaffolds. Scale bars = 50 μm. G–I Two-dimensional AFM images of SF, SF/ASC–ECM, and SF/ASC–ECM–Fe3O4 NP–VEGF scaffolds. Scale bars = 0.5 μm. J–L Three-dimensional AFM images of SF, SF/ASC–ECM, and SF/ASC–ECM–Fe3O4 NP–VEGF scaffolds. M Representative stress/strain curves for SF, SF/ASC–ECM, and SF/ASC–ECM–Fe3O4 NP–VEGF scaffolds. N Comparison of the maximum load of the three scaffolds. Statistical analysis is shown as ★p < 0.05, ns no significance.
