VPA enhances axon outgrowth in a concentration dependent manner. (A) Spinal neurons were stained with antibodies to β-III tubulin (red) and digital images were taken for morphometrical analysis. (B) The length of axon was determined and average outgrowth was calculated. VPA attenuated the inhibitory effect of Nogo-A and enhanced neurite regeneration in a concentration dependent manner. Neurite outgrowth was expressed as a ratio to control and presented as mean±SEM (n=3). Bar=100 μm, and p<0.05*, p<0.01** as compared to Nogo-A group; p<0.05# as compared to control group.
