Figure 8. Immunolabeling and quantification of peptidergic and non-peptidergic primary sensory neurons in the C7 dorsal root ganglia.
Representative section of the ipsilesional and contralesional C7 DRGs of naïve rats (A, G), SCI No Allodynia (B, H), SCI Allodynia (C, I), SCI No Allodynia + Ex (D, J), and SCI Allodynia + Ex (E, K) reacted for calcitonin gene-regulated peptide (CGRP) and Isolectin-B4 (IB-4) at 56 dpi. All groups exhibit similar distribution of CGRP+ and IB-4+ DRG neurons in the ipsilesional and contralesional C7 DRG (F, L; p>.05, dashed line indicates naïve levels). Scale bar = 30 microns.
