Brain-derived neurotrophic factor expression in human intervertebral disc tissue. Brain-derived neurotrophic factor (BDNF) protein expression was identified in (a), (c) the chondrocyte-like cells of human nucleus pulposus and inner annulus fibrosus tissue, and (e) the fibroblast-like cells of the outer annulus fibrosus. (b), (d), (f) IgG controls were negative. Scale bar = 50 μm.
