(A) The diameter of individual topographical features on the surface of the aligned collagen scaffolds. The diameter was significantly affected by the initial conduit diameter with posthoc tests revealing that only the largest conduits produced a significant difference (P < 0.0001). (B) The collagen concentration of the hydrogel suspension did not significantly affect the diameter of topographical features (P = 0.5439). (C) Freezing temperature significantly affected the diameter of individual fiber-like features (P < 0.0001).
