Expression of 5-HT2AR in spinal motoneurons. (A) Immunofluorescence staining of 5HT-2CA and ChAT in the spinal cord of rats from different groups. (B) Co-localization density of 5-HT2AR and motoneurons, n = 6 SCI-N + I group, n = 3 in SCI group, and n = 4 in the sham group (130 ChAT-positive neurons in eight visual fields in the sham group, 96 ChAT-positive neurons in six visual fields in the SCI group, 292 ChAT-positive neurons in 17 visual fields in the SCI-N + I group). *Represents the significance of the difference between groups (one-way ANOVA, Bonferroni’s post hoc test). One, two, and three symbols indicate P < 0.05, P < 0.01, and P < 0.001, respectively.
