Formulation and characterization of mdECM hydrogel. A) Schematic elucidating preparation of hydrogel based on early chondrogenic mdECM. B) Scanning electron micrographs (SEM) of crosslinked mdECM hydrogel. Magnifications of 10 000× (at left) and 40 000× (at right). C) Steady shear flow behavior of the hydrogel under an isothermal up and down shear rate ramp at 15 °C. D) Transient shear recovery behavior of the hydrogel under isothermal stepwise changes in the shear rate at 15 °C. Thermal‐induced gelation of the hydrogel as determined by linear viscoelasticity tests E) and by the loss factor (G′′/G′) F) of the hydrogels from 20 to 40 °C. Data represent mean ± S.D. (n = 3).
