Figure 4From: Expression of semaphorin 3A and its receptors in the human intervertebral disc: potential role in regulating neural ingrowth in the degenerate intervertebral discHistogram illustrating the percentage of cells positive for sema3A in post-mortem degenerate samples and surgical degenerate 'painful' samples. Values are mean ± SEM. *P < 0.05.Back to article page
