Posterior vertebral body height versus spinal level and age for B6 and TSK mice. Posterior height versus spinal level at different ages (a, b; purple arrow shows the thoracolumbar junction) and versus age at different spinal levels (c, d), shown for B6 (a, c) and TSK (b, d) mice. The vertebrae of the TSK mice appear shorter than those of the B6 mice at 4 weeks, but then appear to grow more rapidly than those of the B6 mice and by 12 weeks are noticeably longer than the B6 mice particularly in the lumbar region (statistical analysis shown in Supplementary Data).
