Figure 5. (A) Scaffold degradation over time (i) and swelling ratio (ii). Results are represented as mean ± SD (n = 25 in the degradation assay, and n =
10 in the swelling assay). (B) Mechanical characterization of the acellular scaffolds (purple) and tissue constructs (orange): (i) stress (kPa) vs. strain (%)
curves, (ii) work to break or maximum (mJ), (iii) tangent elastic modulus (kPa), and (iv) maximum stress (kPa). This characterization was performed with
a compression test at different time points. Results are represented as mean ± SD (n = 4). *p < 0.05.
