PDA-HP hydrogel treated under NIR laser irradiation could improve the mitochondrial function. (A) ATP level assay of spinal cord tissue samples of various groups. The data of our experiments are reported as mean value ± SD (n = 6, nsp = 0.6466, and ∗∗∗p < 0.001). (B) MDA assay of spinal cord tissues in various groups. The data of our experiments are reported as mean value ± SD (n = 6, ∗p = 0.0427, and ∗∗∗ p < 0.001). (C) LDH assay of ND7/23 cells in various groups. The data of our experiments are reported as mean value ± SD (n = 6, ∗ p = 0.0443, and ∗∗∗∗ p < 0.0001). (D) Results of MMP measured by JC-1. Scale bars are 50 μm. (E) The statistical chart of the ratio of JC-1aggregates to JC-1 monomers in various groups. The data of our experiments are reported as mean value ± SD (n = 6, ∗∗∗ p = 0.0004, and ∗∗∗∗ p < 0.0001). (F) Immunofluorescence of ROS in various groups. Scale bars are 100 μm. (G) The statistical chart of DCF fluorescence. The data of our experiments are reported as mean value ± SD (n = 6, ∗ p = 0.0182, and ∗∗∗∗ p < 0.0001).
