Abstract by Jennifer Z Paxton:
Tissue engineering is an emerging field of research focussed on the manufacture of body tissues and organs in the laboratory. It combines the basic principles of biology with engineering and materials science to produce tissue-like structures with the potential for implantation. While research within tissue engineering is making significant advances, a major drawback regarding the implantation of tissue-engineered structures remains the creation of suitable tissue interfaces. This is extremely relevant within the musculoskeletal field, where the main function of the tissue is to generate or transmit force. Without suitable mechanical and biochemically graded transitions between the tissues of muscle, tendon, ligament and bone, stress and strain concentrations would cause tissue injury and in the case of an implanted tissue, certain implant failure. For example, clinically, bone to tendon/ligament healing results in a weak interface, formed mainly of scar tissue, which does not possess the graded structure present in native tissue. 
This talk will describe the current progress in engineering tissue interfaces in the laboratory and will also examine the methods currently under investigation to achieve the ultimate goal of functional tissue replacement.
