Rhelogical properties of 0.5 wt% peptide gels (25 mm HEPES 0.5× DMEM pH 7.4, 37 °C). (A) Dynamic time sweeps (frequency = 6 rad/s, 0.2% strain) of MAX8, HIT2 and HLT2 hydrogels. (B) Shear-thin recovery of MAX8 and HLT2 gels; the first 10 min represents the onset of gelation (0.2% strain, 6 rad/s). After which, gels are shear-thinned at 1000% strain for 30 s and allowed to recover by reducing the strain to 0.2%. (C) Distribution of primary chondrocytes in 0.5 wt% MAX8 (I) or HTL2 (II) hydrogels after syringe delivery. Cells were labeled with CellTracker™ green CMFDA and encapsulated at a density of 1.25 × 106 cells/mL. LSCM images were taken at 5 h post delivery; cells are viewed perpendicular to the Z-axis. Scale bar = 100 µm.
