PBM promotes neuronal survival and motor function recovery after SCI. A, B Immunofluorescence was used to stain neurons at 7, 14, and 28 days after SCI. Compared with the injured group, PBM can promote the survival of neurons (n = 3 per group). Scale bar, 200 μm. C The BMS score was used to evaluate the recovery of motor function in mice at 1, 3, 7, 14, and 28 days after SCI (n = 6 per group). D, E At 28 days, the footprints of each group were obtained by gait analysis, The average step length is counted (n = 6 per group). *P < 0.05, ***P < 0.001, ***P < 0.001, ****P < 0.0001
