摘要
Repair and regeneration of articular cartilage has always been a major challenge in the medical field due to its peculiar structure(e.g.sparsely distributed chondrocytes,no blood supply).Cartilage tissue engineering is one promising strategy for cartilage repair,however,one critical issue for cartilage tissue engineering is the integration between tissue-engineered and native cartilage.In recent years,osteochondral tissue engineering has attracted growing interest for overcoming this problem.Herein,we review the development of osteochondral tissue engineering.Firstly,currently used seed cells in osteochondral tissue engineering will be described.Secondly,several types of scaffolds and their(dis)advantage for osteochondral tissue engineering will be introduced.Thirdly,the growth factors currently used in osteochondral tissue engineering will be presented and discussed.
