Stable solid foam porous scaffolds can be obtained by freeze-drying the Trypsin-obtained (T) DCC. A) Schematic of DCC powder solubilization and freeze-drying. B-C) SEM and gross morphology of porous solid foam scaffolds (15 mg/ml) and their appearance after being in contact with DPBS, or C) Cell culture media. D-G) Trypsin-obtained (T) DCC-based scaffold material characterization, D) SEM images of scaffolds fabricated from DCC at different concentrations. E) swelling ratio depending on the composition of the freeze-dried solution (n = 3), E) Rheology of hydrated samples on the composition of the freeze-dried solution (n = 3 to 6). F) Stability of scaffolds (15 mg/ml) in DPBS and at treatment with collagenase (n = 3). Data were similar when cell culture media was used.
