Figure 6: 3D characterization of the endplate at different ages.

(A) Vertical view of the 3D pseudo-color image of the endplate among mice of different ages. (B) Quantification of the endplate thickness and porosity after aging. A = anterior; C = center; P = posterior. The pseudo-color bar in the lower-right corner indicates the diameter ranges of the endplate thickness. Data are the means ± S.D., n = 8 mice in each group. In panel (B), a indicates a significant difference between the posterior region and the center region, and b indicates a significant difference between the posterior region and the anterior region (p < 0.05, determined by two-way repeated measures ANOVA with Bonferroni’s post hoc test).
