The mechanical properties of bioprinted constructs crosslinked in different concentration of β-GPS. a) Young's modulus of bioprinted constructs with β-GPS in 0.3 M, 0.6 M, 1.0 M, and 1.3 M. b) Young's modulus for the bioprinted constructs with 0.6 M and 1.0 M in cell culture condition on 1 day, 7 days, 14 days, 21 days. c) Porosity of bioprinted constructs crosslinked with β-GPS in 0.3 M, 0.6 M, 1.0 M, and 1.3 M. d) The images of SEM for bioprinted constructs crosslinked with β-GPS 0.3 M, 0.6 M, 1.0 M, and 1.3 M after freeze-drying. *** indicates significant statistical difference (p < 0.001) with those of group of 0.6 M; NS indicates no statistical significance.
