JYH-HORNG, WANG (王至弘) by sharon, 2011-01-26 15:07, 人氣(246) ASSISTANT PROFESSOR As an orthopaedic surgeon specializing in sports medicine, my clinical practice and research interest are focused on the related studies concerning cruciate ligament reconstruction. We have published papers about ligament biology, biomedical materials and tissue engineering in orthopaedics (J Biomed Mater Res 2007; Biochem Biophys Res Commun 2007; Artificial organs 2009). We evaluated the phenotypic responses of human ACL (anterior cruciate ligament) cells on two biodegradable materials: PCL(poly ε-caprolactone) and chitosan. And we proposed that the different properties of materials will cause cells to present different responses and the character of chitosan to promote ECM synthesis might be a ideal scaffold for successful ACL tissue engineering. Also, based on the different adhesion characteristics of human ACL cells on chitosan and PCL, our further study is concerned with the gene expression and ECM production of ACL cells through cell shape changes on blends of chitosan with PCL. It is possible to combine the advantages of chitosan and PCL to create a new blended material, which could maintain the viability and stimulate the collagen synthesis of human ACL cells simultaneously. The blended material might be a potential candidate for ACL tissue engineering. • Shao HJ, Chen CS, Lee YT, Wang JH, Young TH: The phenotypic responses of human anterior cruciate ligament cells cultured on poly(ε-caprolactone) and chitosan.
