Spatiotemporal delivery strategies for promoting musculoskeletal tissue regeneration.
A primary regenerative medicine strategy is to stimulate or augment endogenous repair mechanisms that promote functional restoration of damaged or degenerated tissues. There is increasing evidence that maximizing the potency of tissue regenerative therapies will require design and development of delivery approaches that provide controlled spatiotemporal release of key signaling molecules. Guidance on which factors to deliver and the timing of delivery is emerging from advances in understanding of critical pathways involved in the development of integrated musculoskeletal tissues. A broad range of biomaterials-based deployment technologies are becoming available that allow controlled spatial presentation and release kinetics of biological cues. The purpose of this perspective article is to review promising spatiotemporal delivery strategies designed to promote functional tissue regeneration with an emphasis on vascularized bone repair.
