The regenerative wound healing effects and molecular mechanism of Isaria cicadae Miquel rice fermentation extract

Abstract: Human skin wounds primarily heal through reparative wound healing without pilosebaceous units or other appendages, rather than regenerative wound healing. Hair follicle (HF) regeneration is a significant challenge for skin wound healing. The effects and underlying mechanisms of Isaria cicadae Miquel rice fermentation extract (IMFRE) remain unclear, although it has anti-inflammatory, antioxidant, and reparative effects on oxidative damage in keratinocytes. We assessed the regenerative wound healing ability of IMFRE and its related molecular mechanisms through experimental validation and network pharmacology analysis. Our findings suggest that IMFRE could be an important potential solution for regenerative wound healing of skin hair follicle by utilizing the Hippo pathway regulatory mechanism. KEY POINTS: • IMFRE was found to significantly enhance the wound healing rate of mouse skin. • CK15 and CD34 were significantly increased by high-dose IMFRE intervention. • IMFRE could inhibit EGFR, GPCR, and Integrin expression.
