FIG. 5.

Histological assessment of cartilage repair after 12 weeks in vivo. (A, C) Representative images after staining with Safranin-O/fast green and immunohistochemistry for type 2 collagen, respectively. Images shown represent median values for overall histological score and percent type 2 collagen-positive area, respectively (shown in inset). (B) Scoring of histology using ICRS-II system (overall score shown) and (D) quantification of percent positive type 2 collagen-stained area (n = 7–10). *p < 0.05 between specified groups and **p < 0.05 in comparison to all other groups, unless that group is marked with n.s.
