Abstract:

Cartilage tissue engineering appears as an important strategy for repairing articular cartilage. However, it faces the problems of insufficient number of chondrocytes, dedifferentiation in vitro, and difficulty in controlling the direction of differentiation. The co-culture system provides a new solution to these problems. A series of studies have reported that the co-culture system can prevent the dedifferentiation of chondrocytes cultured in vitro, promote the re-differentiation of dedifferentiated chondrocytes, and facilitate the chondrogenic differentiation of stem cells in the system as well as inhibit the process of hypertrophy. This review summarized the literatures about the application of co-culture system in cartilage tissue engineering, discussed the role of co-culture system in cartilage tissue engineering, and explored the underlying mechanism.

Key words: Coculture techniques, Chondrocytes, Tissue engineering
