Immunohistochemical staining of PGP 9.5 at 6 months after surgery. The intact AF showed sparsely PGP 9.5-positive nerves distributed within the outermost layers of the AF (a). The punctured disc exhibited positive staining for PGP 9.5 scattered in superficial areas of the scar tissue (b). Small nerves were detected in the deeper outer AF along the fissures toward the NP (c). Nerves were seen deep within the inner AF, in close proximity to blood vessels (d)
