Characteristics of osteogenesis and chondrogenesis factors during osteochondral defect repair. Subchondral bone tissue from the four groups was harvested at 4 weeks after surgery and subjected to qRT-PCR to detect the mRNA levels of IGF-1 (A), BMP-2 (B) and b-FGF(C). Repaired cartilage tissue from the four groups was subjected to qRT-PCR to detect the mRNA levels of SOX-9 (D), Collagen II (E), ACAN(F) and N-Cadh(G). The glycosaminoglycan (GAG) content and the DNA content in the repaired cartilage tissue were measured (H and I). Data are represented as mean ± s.e.m. (*p< 0.05).
