Figure 3.

Images showing the surface of scaffolds stained with Safranin O and immunohistochemical labelling for collagen type I, collagen type II and collagen type X after 4 weeks of culture. Images (a), (b) and (c) show Safranin O‐stained control scaffolds from Uniform, Asymmetric and Surface Only seeded scaffolds, respectively, while images (d), (e) and (f) show Safranin O‐stained loaded scaffolds. Images (g), (h) and (i) show control scaffolds labelled for collagen type I, and images (j) (k) and (l) show loaded scaffolds. Images (m), (n) and (o) show control scaffolds labelled for collagen type II and images (p), (q) and (r) show loaded scaffolds. Images (s), (t) and (u) show control scaffolds labelled for collagen type X and images (v), (w) and (x) show loaded scaffolds. [Colour figure can be viewed at http://wileyonlinelibrary.com]
