Expression of synaptophysin and synaptoporin in dorsal cutaneous C fibers in the T7 and T13 spinal cord. Cutaneous C fibers were labeled with IB4 injections into DCNs. (A) DCN-specific C fibers projected laterally at the inner layer of laminae II overlaid by the synaptoporin distribution area as shown in representative montages of confocal images at T7. (B) Overlapping areas of DCN-specific IB4+ C fibers with synaptoporin and synaptophysin were quantified at every 200 μm across the sections centered at the dorsal horn entry zone (DREZ) at T7 and T13. (C) Bar graphs show averaged percent overlapping areas across those serial sections from 3 rats (D).
