OBJECTIVE: The interrelationship between various growth factors and chondrocytic regeneration has drawn the attentions of scholars and the study on growth factors and repair of articular cartilage defects has been carried on to summarize the latest progression of transforming growth factor-β (TGF-β) in articular cartilage repair so as to provide theoretical evidence for its application in cartilage histoengineering.DATA SOURCES: The relevant papers about studies on mechanism and types of articular cartilage injury, TGF-β and interrelationship between TGF-β and articular cartilage repair were looked up on http:∥www.ncbi.nlm. nih.gov/PubMed from January 1995 to December 2004. The retrieval words were "TGF-β, articular cartilage" limited only in English version.The relevant papers about studies on TGF-β and articular cartilage repair were also looked up on http:∥www.zglckf. com and linked database from January 1999 to December 2004, with the retrieval words of "TGF-β, articular cartilage" limited only in English version.STUDY SELECTION: During the initial evaluation of data and after looking up the quotation of each paper, the inclusive criteria were determined as follows: the paper should be relevant with TGF-β repair of articular cartilage injury; and the exclusive criteria: repeated research and Meta analysis papers. The papers that had not been excluded applied randomized design, control and blind comparison.DATA EXTRACTION: Altogether 95 papers were collected on TGF-βand TGF-β repair of articular cartilage injury, of which, 15 papers were in conformity of inclusive criteria, 56 papers were excluded due to dated research and 24 papers were due to repeated research. Of 15 papers, 3 papers were on the mechanism and types of articular cartilage injury, 6 papers were on biological function of TGF-β and 6 papers were on TGF-βand TGF-β repair of articular cartilage injury.pact, cut, torsion and friction, which is beyond the physiological endurance of articular cartilage. Articular cartilage defects are divided into defects of partial thickness and entire layer of cartilage. The auto-repair growth factor with various functions, which is produced by either autocrine or paracrine. It starts transmitting information by integrating with lagen and stromatin by irritating osteocytes and chondrocytes to form rapidly extracellular matrix so as to promote repair of bone and cartilage injury.CONCLUSION: TGF-β plays the importance in histoengineering repair of articular cartilage injury. By bringing induction of cartilage into play,TGF-β promotes differentiation of stem cells into cartilage or enhances specific matrix synthesis of cartilage, such as collagen Ⅱ and proteoglycan. Due to the limitation of various repair methods of cartilage defects at present, being a cell factor with good cartilage induction, TGF-βwill present extensive prospects in the application of cartilage histoengineering.
