摘　　要：In current clinical practice,various dermal templates and skin substitutes are used to enhance wound healing.However,the role of wound commensal microbiome in regulating scaffold performance and the healing process remains unclear.In this study,we investigated the influence of both natural and synthetic scaffolds on the wound commensal microbiome and wound repair in three distinct models including diabetic wounds,burn injuries,and germ-free(GF)wounds.Remarkably,synthetic electrospun polycaprolactone(PCL)scaffolds were observed to positively promote microbiome diversity,leading to enhanced diabetic wound healing compared to the natural scaffolds Integra(INT)and MatriDerm(MAD).In contrast,both natural and synthetic scaffolds exhibited comparable effects on the diversity of the microbiome and the healing of burn injuries.In GF wounds with no detectable microorganisms,a reversed healing rate was noted showing natural scaffold(MAD)accelerated wound repair compared to the open or the synthetic scaffold(PCL)treatment.Furthermore,the response of the wound commensal microbiome to PCL scaffolds appears pivotal in promoting anti-inflammatory factors during diabetic wound healing.Our results emphasize that the wound commensal microbiome,mediated by different scaffolds plays an important role in the wound healing process.
