It is well-understood that wound care poses a significant burden on the healthcare system and patient well-being. As such, it is imperative to develop efficient methods that facilitate tissue repair. Our group previously developed a nutritional gel scaffold, proven to accelerate wound repair. Due to its gel-like properties, this scaffold requires a time-consuming reconstitution, and is optimized for cavernous wounds. This pilot study examined the feasibility of a powdered form of this scaffold to accelerate healing of full-thickness wounds, thus broadening the range of applications, while providing a practical product. Splinted full-thickness wounds were generated on the backs of 6 mice, and treated with either powder, the original gel scaffold, or no treatment. Feasibility and efficacy of the powder was assessed through comparison of clinical wound measurements and histological assessments. There was a significant effect of treatment on rate of epithelialization [H(3) = 8.346, p = 0.0024] and on days to epithelial closure [H(3) = 8.482, p = 0.0061]. Post hoc analysis revealed that while requiring no reconstitution and simple to apply, the powder was sufficient to accelerate epithelialization compared to untreated wounds (p < 0.05). Furthermore, our results suggest that application of this powder did not alter certain processes associated with healing progress, such as epidermal thickness and collagen deposition. As such, this powder may provide a novel alternative to our previously developed gel scaffold by accelerating epithelialization, while providing a practical product. Future studies necessitate further evaluation of healing measures with a larger sample size.
