Rheological properties of the synthesised bioinks. (a) Oscillatory amplitude sweep results showing the G′ and G″ evolution over strain. (b) G′ recovery of the bioinks after being put under a high strain to mimic the extrusion process. (c) G′ of each condition after being cross-linked for 15 or 10 min corresponding to the sCL and wCL protocols, compared to the non-cross-linked samples. (d) G′ loss of the two cross-linkings studied after 7 and 14 days in culture. Different letters indicate statistically significant differences between time points in the same condition, different numbers indicate statistically significant differences between conditions, and different symbols indicate statistically significant differences between cross-linkings (p < 0.05).
