SEM images demonstrate how the fibroblasts are interacting directly with the nanostructures. (a) Fibroblasts grown on P(flat). (b) Fibroblasts grown on P(20). (c) Fibroblasts grown on S(flat). (d) Fibroblasts grown on S(5). (e) Fibroblasts grown on S(0.88). (f) Fibroblasts grown on S(0.5, 1.4, 3.4). Similarly to Figure 5, the P(20) and S(5) nanostructured surfaces induce a rounded morphology, indicating an antifibrotic environment. The scale bars are 10 μm.
