Biomaterials for Tissue Sealing and Wound Repair
Complications associated with ineffective tissue repair in slow or non-healing wounds, including diabetic wounds, cost the US healthcare system ~$20 billion / year and amount to ~5% of the total cost of Medicare and Medicaid. In cases of surgical closure, lack of immediate tissue approximation, high potential for scarring, including in visible areas of the body, susceptibility to infection, and long procedure times necessitate new approaches for tissue repair especially for unmet needs where current approaches are suboptimal in performance. Light-activated tissue sealing is an emerging strategy that facilitates rapid, liquid-tight approximation of ruptured tissues, but the lack of effective biomaterials compromises efficacy. I will discuss our advances in the generation, characterization, evaluation, and of laser-activated sealants (LASEs), and their use in bioactives delivery, for the rapid sealing and repair of incisional wounds and infection control, including in diabetic and obese hosts. In addition to acute trauma, slow-healing and chronic wounds, including in diabetic and obese patients, are a significant cause for morbidity. Advanced treatments, including biologics, have shown some promise but have largely not succeeded in cases of intractable wound pathologies. I will describe our new findings on the delivery of immunomodulating bioactive molecules and polypeptide biomaterials in combination with growth factor nanoparticles with an eye towards developing a temporal delivery strategy for specifically modulating individual stages of tissue repair, leading to accelerated healing, including in diabetic and obese mice. Taken together, our studies demonstrate that biomaterials, in concert with delivery of light
and bioactive molecules, show strong promise for accelerating wound healing as well as efficacious tissue sealing and repair.
