Recent studies have shown the importance of transforming growth factor-beta (TGF-beta) in flexor tendon wound healing. Decreased adhesion formation and increased range of motion after the administration of TGF-beta antibodies after tendon repair have been shown. But TGF-beta antibodies have a short biologic half-life, and continuous supplementation of exogenous TGF-beta antibodies is not practical. Transfer of growth factor genes to tenocytes provides an alternative to protein therapeutics, and a gene therapy approach will prolong the availability of therapeutic proteins.We investigated the biological activities effects of rabbit tendon sheath fibroblasts transfected by antisense TGF-beta1 gene. Tendon sheath fibroblasts were isolated from …
