In vivo functional and histological assessment. (A) Representative images of spinal sections from H&E staining in each group at 6 weeks postinjury. (B) General anatomical analysis of whole spinal cords. (C) Quantification analysis of the lesion site of spinal sections from H&E staining. (D) Photos of forelimb (red) and hindlimb (blue) footprints in each group at 6 weeks postinjury (yellow arrow pointed the posterior limb prints). (E) The BBB scores of the different groups at different time points. (F) The behavior assay of IPT scores at 6 weeks postinjury. (G) Immunofluorescence images by double staining with GFAP/5-HT in each group. (H) Quantification of 5-HT⁺ axons at the SCI sites.
