FIG. 6.

Histology images showing the development of neovasculature in inverse opal scaffolds. Hematoxylin and eosin-stained sections of the explanted scaffolds with a pore size of (A–D) 200 μm and (E–H) 80 μm postimplantation at (A, E) 2 weeks, (B, F) 4 weeks, and (C, D, G, H) 6 weeks. Sections in (A–C, E–G) were obtained from the central region (500–1000 μm below surface) of the scaffolds, while sections in (D, H) were obtained from a plane close to the surface (0–200 μm). Arrowheads denote blood vessels. Color images available online at www.liebertpub.com/tec
