Representative images of IHC staining of osteo-chondrogenesis markers, OPN, OCN, Col II, and SOX9 in CG and DG tendons at weeks 1, 2, and 4 post-STZ induction. The osteogenic markers OPN and OCN were both positively expressed in DG tendons (2a–2f, arrows) at weeks 1, 2, and 4 while the controls were negatively expressed (2A–2F). The chondrogenesis markers Col II and SOX9 were also positively expressed in DG tendons (2g–2 l, arrows) at weeks 1, 2, and 4 while the controls were negatively expressed (2G–2L). n = 6 of each group. Scale bar = 100 μm
