Description
Summary:Atopic dermatitis (AD) is a chronic inflammatory skin condition characterized by impaired barrier function and persistent inflammation, necessitating advanced therapeutic solutions. This study presents the development of a novel composite hydrogel scaffold composed of polyvinyl alcohol (PVA), gelatin, and <i>Cnidium monnieri</i> (CM) extract, designed to address the dual challenges of tissue regeneration and inflammation suppression. Fabricated via optimized freeze–thaw crosslinking and lyophilization, the scaffold exhibited a highly porous structure conducive to enhanced cell proliferation and controlled bioactive release. FT-IR analysis confirmed robust intermolecular interactions among PVA, gelatin, and CM bioactives, while SEM imaging revealed a well-developed porous network. The UPLC analysis demonstrated the sustained release of key CM compounds, such as osthole and imperatorin, which contributed to the scaffold’s anti-inflammatory properties. Biological assessments using HaCaT keratinocytes under inflammatory conditions induced by TNF-α and IFN-γ revealed improved cell viability and significant suppression of IL-8 expression, a critical marker in AD-related inflammation. These findings underscore the potential of the PVA/Gel/CM composite hydrogel as an advanced therapeutic platform for inflammatory skin disorders.
