Current Advancements and Strategies in Tissue Engineering for Wound Healing: A Comprehensive Review

Jasmine Ho et al. Adv Wound Care (New Rochelle). .

Abstract

Significance: With an aging population leading to an increase in diabetes and associated cutaneous wounds, there is a pressing clinical need to improve wound-healing therapies. Recent Advances: Tissue engineering approaches for wound healing and skin regeneration have been developed over the past few decades. A review of current literature has identified common themes and strategies that are proving successful within the field: The delivery of cells, mainly mesenchymal stem cells, within scaffolds of the native matrix is one such strategy. We overview these approaches and give insights into mechanisms that aid wound healing in different clinical scenarios. Critical Issues: We discuss the importance of the biomimetic niche, and how recapitulating elements of the native microenvironment of cells can help direct cell behavior and fate. Future Directions: It is crucial that during the continued development of tissue engineering in wound repair, there is close collaboration between tissue engineers and clinicians to maintain the translational efficacy of this approach.

Keywords: biomimetic; tissue engineering; wound healing.

Representation of the number of studies that adopt various approaches to wound healing. Percentage of studies applying either of the following: cells directly to the wound, growth factors directly, or a scaffold, as well as those that combine these approaches, that is, scaffold with encapsulated cells, scaffolds with encapsulated growth factors, and all three combined or cells with additional growth factors.
