In vitro biocompatibility of DNNA. (A) Livability of SCs encapsulated in HA-TU-Cat and DNNA hydrogels after 7 days. Red: dead cells; green: live cells. (B) Proliferation of SCs encapsulated in HA-TU-Cat and DNNA hydrogels tested by CCK8. (C) Axonal outgrowth from DRGs on HA-TU-Cat and DNNA hydrogels. Red: TUBB3 stained axon; blue: DAPI stained nucleus. (D) Maximum axonal extension distance from DRGs on HA-TU-Cat and DNNA hydrogels. 20–30 axons from 4 DRGs were included in each group. All quantitative data are expressed as the mean ± standard deviation. Asterisks indicate statistically significant comparisons, ****p<0.0001, by Student’s t-test.
