Abstract
Cutaneous wound healing remains a significant clinical challenge, particularly for chronic and large-scale injuries, where functional recovery-especially sensory reinnervation-is often inadequate. Recent advances highlight the pivotal role of innervation in regulating tissue repair through neuropeptide signaling, immunomodulation, and angiogenesis. Despite progress in biomaterial-based therapies, most existing solutions focus on structural repair while neglecting neural regeneration, leading to suboptimal functional outcomes. This review explores emerging biomaterial strategies that integrate neuroregenerative capabilities with wound healing properties, including electroconductive scaffolds for bioelectric stimulation, neurotrophic factor-releasing matrices, and bioengineered constructs. We critically evaluate their mechanisms in promoting axonal regrowth, macrophage polarization, and vascular network formation, while addressing challenges in long-term functional integration. This review outlines the mechanisms of wound healing, existing treatments, and the vital role of nerves in the healing process. It also highlights materials that promote skin neuralization in cutaneous wound healing, aiming to inspire further research into these materials and the underlying mechanisms involved. By bridging the gap between neural and cutaneous regeneration, this work provides a roadmap for developing next-generation wound therapies that restore both structural integrity and sensory function. Future directions emphasize the need for standardized neuroregenerative assessment criteria and clinically translatable designs.
