Typical compressive stress-strain curves for tests performed parallel to the long cylinder axis of samples from the upper regions of (A) dry (inset magnifies initial slope region) and (B) fully hydrated collagen scaffolds freeze cast at three different applied cooling rates (0.1 °C/min, 1 °C/min, and 10 °C/min). Typical compressive stress-strain curves for tests performed perpendicular to the long cylinder axis of samples from the upper regions of (C) dry and (D) fully hydrated collagen scaffolds.
