FAST profiles of growing mouse intervertebral discs. The coccygeal intervertebral discs of newborn mice (A–C) and 10-day-old (D–F), 4-week-old (G–I), and 8-week-old (J–L) mice were stained using the standard FAST protocol. The nucleus pulposus (B,E,H,K) and annulus fibrosus (C,E,I,L) are also shown under a higher magnification. GP, growth plate; NP, nucleus pulposus; AF, annulus fibrosus; SC, spinal cord; EP, cartilaginous endplate; IA, inner annulus; OA, outer annulus; SA, superficial annulus.
