Golgi-stained dendritic spines on spinal motor neurons from Sham-Rac1wt, Sham-Rac1KO, SCI-Rac1wt, and SCI-Rac1KO. A, Golgi staining of the spinal cord labels α-motor neuron located in Rexed lamina IX (dashed line). B, A reconstructed segment of Golgi-stained motor neuron dendritic branch showing dendritic spines from Sham-Rac1wt, Sham-Rac1KO, SCI-Rac1wt, and SCI in astrocytic Rac1KO. Scale bars in A = 50 µm and B = 10 µm.
