Influence of basic fibroblast growth factor on tissue repair and reconstruction after fracture / 中国组织工程研究

ABSTRACT

BACKGROUND: Basic fibroblast growth factor (BFGF) widely in human tissue participates in trauma repair of various tissues and is one of wound healing factors in the body. OBJECTIVE: To summarize the progress of BFGF in the fracture healing. RETRIEVAL STRATEGY A computer-based online search of Pubmed Database was undertaken to identify the relevant articles on BFGF in the fracture healing published from January 2000 to December 2007 with the Keywords of "fibroblast growth factor 2 (basic fibroblast growth factor), fracture healing, regulation, signal transduction" in English. At the same time, Chinese relevant articles were searched in China Journal Full-text Database (CJFD) and Wanfang Database published between January 2000 and December 2007 with the same key words in Chinese. Exclusive criteria included articles with repetitive research and non-original study. LITERATURE EVALUATION A total of 33 articles were collected about the distribution (3 articles), biological characteristics (3 articles) and the effect on the healing of bone fracture (27 articles) of BFGF. DATA SYNTHESIS: Bone healing is the process of regeneration after bone injury and the process of bone formation. BFGF can promote the cell migration by its chemotaxis and accelerate the healing by aggregating mesenchymal stem cells, macrophage and fibroblasts towards trauma region. Present animal studies on BFGF are deep and reports on clinical application are a few. Thus, the effect of BFGF is available. BGFG can affect bone formation by adjusting cell prolifeation and differentiation and changing the synthesis of cell products. BGFG not only can promote the bone growth, but also enhance the adhesion of osteoblasts and scaffold. CONCLUSION: The distribution and biological characteristics of BGFG have been recognized primarily. The further study on modulatory mechanism in the fracture healing of BFGF is carrying through. The bone restoration compounded by BFGF and its carriers is in the experiment and needs to be studied further.
