Neuron-derived exosomes promoted functional behavioral recovery after SCI. a BMS was used to functionally grade in the PBS and Exos groups at 28 days after SCI for mice. b The footprints quantification of mice walking 28 days after SCI. Blue: frontpaw print; red: hindpaw print. c MEP was carried out as an electrophysiological assessment in two groups at 28 days after SCI. d Photographs of the various degrees of trunk instability (TI) that were observed after SCI surgery, and statistical analysis of the Louisville Swim Scale in the Exos and PBS groups over a 28-day period. e Representative Nissl-stained sagittal section of spinal cord. f Immunostaining of NF200 and GFAP in the injured areas of spinal cord at 28 days after SCI. *P < 0.05
