MMP-9 Contributes to Dendritic Spine Remodeling Following Traumatic Brain Injury
Figure 3
Effect of lack of functional MMP-9 on spine density in animals after controlled cortical impact (CCI). (a) Spine density in ipsi- and contralateral 2nd and 3rd cortex layers of animals with different mmp-9 gene expression levels 1 week after CCI and sham surgeries; upper panel shows representative dendrites pictures. (b) Spine density in the ipsi- and contralateral dentate gyrus of animals with different mmp-9 gene expression levels 1 week after CCI and sham surgeries; upper panel shows representative dendrite pictures. Data are presented as . Statistical analysis was carried out using one-way ANOVA followed by Tukey’s post hoc test. Asterisks indicate statistical significance from the CCI and sham groups, respectively. .
