(A) GFP-expressing rat dermal fibroblasts cultured on random collagen scaffolds fabricated in low aspect ratio vessels showing no preferential alignment. (B) However, GFP expressing rat dermal fibroblasts cultured on aligned collagen scaffolds elongate and orient parallel to the features on the aligned collagen scaffolds (arrow indicates direction of aligned scaffold features). (C and D) Alignment of GFP expressing rat dermal fibroblasts on aligned collagen scaffolds was quantified, and the average alignment factor was found to be close to 1 on aligned collagen scaffolds.
