RT Journal Article SR Electronic T1 Tissue engineering for tendon repair JF British Journal of Sports Medicine JO Br J Sports Med FD BMJ Publishing Group Ltd and British Association of Sport and Exercise Medicine SP e10 OP e10 DO 10.1136/bjsm.2006.030643 VO 41 IS 8 A1 Pierre-Olivier Bagnaninchi A1 Ying Yang A1 Alicia J El Haj A1 Nicola Maffulli YR 2007 UL http://bjsm.bmj.com/content/41/8/e10.abstract AB Tissue engineering aims to induce tissue self-regeneration in vivo or to produce a functional tissue replacement in vitro to be then implanted in the body. To produce a viable and functional tendon, a uniaxially orientated collagen type I matrix has to be generated. Biochemical and physical factors can potentially alter both the production and the organisation of this matrix, and their combination in a dose- and time-dependent manner is probably the key to in vitro engineered tendons. This review discusses the role of these different factors affecting tenocyte growth in a three-dimensional environment in vivo and in vitro, and underlines the future challenge of tendon tissue engineering.
