Immunohistochemical staining of repaired tissue showing Col1 and Col2. (A-D) Immunohistochemical staining of Col1 in repaired tissues. (A, B) Full-thickness chondral defects of 6.5 mm diameter and 8.5 mm diameter in immunohistochemical staining of Col1. (C, D) Osteochondral defects of 6.5 mm diameter and 8.5 mm diameter in immunohistochemical staining of Col1. (E-H) Immunohistochemical staining of Col2 in repaired tissues. (E, F) Full-thickness chondral defects of 6.5 mm diameter and 8.5 mm diameter in immunohistochemical staining of Col2. (G, H) Osteochondral defects of 6.5 mm diameter and 8.5 mm diameter in immunohistochemical staining of Col2. (The results are represented as the mean ± standard deviation. n = 3, *, P < 0.05; **, P < 0.01; ***, P < 0.001. Scale bar: 200 μm.)
