Canine intervertebral disc and vertebrae sections stained by hematoxylin/eosin staining. (A) A section of a healthy intervertebral disc with a healthy gelatinous nucleus pulposus core. (B) An artificially degenerated disc section with a fibrous nucleus pulposus core. Degeneration was induced by aspirating approximately 25 mg of nucleus pulposus tissue by methods from previously published work [74]. Fourteen weeks after aspiration, the tissue was explanted and stained.
