(a) Compressive modulus of CHI-100, CHI-90, and CHI-80 scaffolds. The values represent mean ± standard deviation, n = 4. ^∗indicates p < 0.05 vs. PEG-100 and PEG-90; PEG-100, and PEG-80. (b) The dry-based water content of CHI-100, CHI-90, and CHI-80 scaffolds. The values represent mean ± standard deviation, n = 4. ^∗indicates p < 0.05 vs. PEG-100 and PEG-90; PEG-100, and PEG-80.
