a Live-dead staining of CMs on CPA hydrogel, CPAM hydrogel, and CPAMC hydrogel after 500 μM H2O2 treatment (above). The detection of ROS level in CMs on CPA hydrogel, CPAM hydrogel, and CPAMC hydrogel after 500 μM H2O2 treatment (bottom). b Polarization of RAW264.7 cells on different hydrogels after 24 hours of LPS treatment at 100 ng/mL. c CMs activity (n = 3 independent samples), d SOD level (n = 3 independent samples), and e MDA level (n = 4 independent samples) of CMs on different hydrogels after 500 μM H2O2 treatment (error bar means the standard deviation, *p < 0.05, **p < 0.01, ***p < 0.001, p value was generated by one‐way analysis of variance (ANOVA), followed by Tukey’s multiple‐comparison post hoc test, n = 4 independent samples). CAP, CPAM, CPAMC: C, aldehyde cellulose (CNC-CHO); P, polyethylenimine (PEI); A, acrylic acid; M, 3-sulfonic acid propyl methyl acrylic acid potassium (MASEP); C, caffeic acid (CA).
