Advancement in the tissue engineering of tendon/ligament has become very much a materials engineering problem than ever, with the selection of appropriate biomaterial and scaffold architecture.
It is therefore clear that advancement in the field depends very much upon strategic application of materials engineering knowledge, involving the selection of appropriate biomaterial and scaffold architecture.
However, these materials have exhibited poor mechanical strengths and short degradation periods, both of which are disadvantageous as properties for scaffold materials in the development of tissue engineered tendon/ligament [4].

Study on Tissue Engineering Scaffolds of Silk Fibroin-Chitosan/nano-Hydroxyapatite Composite Guangwu WEN 1, a, Jing WANG 1, 2 , Muqin LI 2 , Xiangcai MENG 2 1 School of Material Science and Engineering, Harbin Institute of Technology, Harbin, 150001, China; 2 Provincial Key Laboratory of Biomaterials, Jiamusi University, Heilongjiang Province, 154007, China a. sdycwjyxd@163.com Key words: SF-CS /n-HA composite; Porosity; Morphology; Tissue engineering Abstract: The porous scaffolds of silk fibroin-chitosan /nano-hydroxyapatite (SF-CS / n-HA) were fabricated through the freeze- drying technique.
Studies suggest the feasibility of using SF-CS /n-HA composite scaffolds for bone tissue engineering.
Introduction The ideal scaffolds for bone tissue engineering should combine excellent cellular affinity, the time-space matching charter of the degradation disappearance of materials and new tissues construction, certain mechanical strength and a three-dimension highly porous microstructure with interconnected pores.
Chitosan is an kind of positive charge alkaline amylose with good biocompatibility and a fast in vivo degradation rate, but poor cellular affinity make it unsuitable as the scaffold of bone tissue engineering alone [4].It was demonstrated that SF had a greater potential for application of clinical repair, tissue engineering and modified materials with a series of excellent characteristics including the same cellular affinity as collagen, good mechanical toughness and minimal inflammatory reaction.
Materials and Methods SF-CS / n-HA (containing 50wt% n-HA) composite powders were synthesized in our laboratory.
