Antioxidant properties assessed as the TEAC (A) and the FRAP (B) of the lyophilized FE002 chondroprogenitor preparations. Results are expressed as means with standard deviations as error bars for six replicates. Storage modulus G′ (C) and loss modulus G″ (D) values of hydrogel combination products at 22 °C and 37 °C, determined by oscillatory rheology at a frequency of 0.5 Hz. Results are expressed as means with standard deviations as error bars for six replicates. Stribeck curves of the hydrogels and of the combination products at 37 °C and with a sliding velocity increase from 0.01 mm/s to 100 mm/s (E). Results are expressed as means with standard deviations as error bars for four replicates. Extremely significant statistical differences (i.e., **** or p-value < 0.0001; *** or 0.0001 < p-value < 0.001) or no statistical differences (ns) were found between the presented mean values. FRAP, ferric reducing antioxidant power; HA, hyaluronic acid; ns, non-significant; TEAC, Trolox equivalent antioxidant capacity.
