Abstract:
OBJECTIVE:To elucidate the role of transforming growth factor-β and bone morphogenetic protein-7 in the reparation of knee cartilage by summarizing related studies,which can provide an important reference for further clinical applications.DATA SOURCES:The science online,ElsecierSD databases,Springer Link electronic joumals nets(1991-01/2009-06)was searched using key words of"Articular Cartilage Defects,Transforming Growth Factor-β,Bone Morphogenic Protein-7";simultaneously,the CNKI,Wanfang database,Tsinghua Tong Fang database(1991-01/2009-06)was searched with the same Chinese key words.Literature search was limited to English and Chinese languages.DATA SELECTION:Literature addressing repairing articular cartilage damage with growth factors was included,and the repeated papers were excluded.MAIN OUTCOME MEASURES:①Frecture healing.②Osteocyte proliferation.③Capacity of chonddfication.RESULTS:Received 95 computers seized in early literature,according to inclusion exclusion criteria,literature underlying growth factor,in particular the growth factor transforming growth factor-β and bone morphogenetic protein-7 in repaidng knee cartilagedamage was analyzed.Articular cartilage injury,with poor repair capacity,is more common in athletes.As soon as a permanent injury that generates lesions,it is difficult to treat by traditional treatment methods,which need to be solved in sports medicine.Transforming growth factor-β,an important factor regulating the formation of cartilage,stimulates or inhibits a variety of cells.By increasing the sensitivity of chondrocytes,transforming growth factor-β plays a central role in the process of repairing osteoarthdtis cartilage injury,regulates in vitro protein synthesis,but also affect on the induction of specific granulation tissues.Bone morphogenetic protein-7 can induces cartilage-specific collagen and mucin production by mesenchymal and wound areas,which has promotive effect on cartilage reparation.CONCLUSION:Transforming growth factor-β or bone morphogenetic protein-7 has certain effect on knee cartilage injury;however,whether the combination of them can promote reparation of articular cartilage injury needs to be explored.
