Figure 3. Aberrant fibrocartilage and presence of osteophytes preceding mineralization in asj-2J mice at 6 weeks of age (white asterisks and arrows).
Toluidine Blue O staining. a. Coronal section of the shoulder region shows large amount of fibrocartilage on the surface of supraspinatus tendon. b. Coronal/sagittal section of knee shows aberrant osteophytes in joint ligament. c. Coronal section of spine shows aberrant osteophytes in intervertebral disc.
