Characterization of ECM deposition in 9 months after implantation. Microscopic photos of cross sections stained with Masson's for collagen (blue, A–C), safranin O for glycosaminoglycansin (red, E–G) and Verhoeff's for elastin (black, I–K) on different scaffolds. Total collagen, GAG, and elastin were assessed by corresponding detection kit respectively (D, H, L) (n = 3). Scale bar: 100 μm. _⁎ indicated statistically significant.
