Immunohistochemistry for vesicular glutamate transporter 1 (VGLUT1). (A–L) Representative images of RZ, RZ+FS and RZ+FS+MC, 1, 4, and 8 weeks post lesion. (M) Quantification (ratio IL/CL) of the integrated density of pixels, obtained in the region delimited by dashed lines. (N) Representation of lamina III (total quantification area 3.9 × 10⁵ μm²). CL, contralateral; FS, fibrin sealant; IL, ispsilateral; RZ, rhizotomy; MC, mononuclear cells. Scale bar = 50 μm. ^*p < 0.05; ^**p < 0.01; ^***p < 0.001.
