摘要 |
Embodiments of surgical grafts, and methods, for the delivery of therapeutic agents to a target tissue via acellular matrices, are described. In some embodiments, nonviable matrices are successful in preventing or lessening adhesion formation by guiding tissue repair and remodeling, while also providing the target tissue with therapeutic agents that can act as repair and remodeling factors. An exemplary method to modulate flexor tendon healing and provide elimination or reduction of fibrotic adhesions involves loading a freeze-dried flexor digitorum longus allograft with recombinant adeno-associated viral (rAAV) vectors for the targeted and transient expression of growth/differentiation factor 5 (GDF5). |
