Change of intervertebral disc histomorphology between young controls and aged rats

The annular fibrosus arranged regularly and more cells were seen in young controls (a) than in aged rats (b). Dead cells in the nucleus gelatinosus were not observed in young controls (c), but were obvious in aged rats (d). Obviously more vascular buds were seen in young controls than in aged rats. Non-clarify layers of young controls (e) were significantly thicker than those of the aged group (f)
