| Summary: | <b>Background/Objectives:</b> Constant inflammation can be a detrimental response in bone regeneration. To regulate of the inflammatory response and synchronically promote rapid tissue regeneration is a vital clinical challenge. The urinary bladder matrix (UBM) and small intestinal submucosa (SIS) composite are commonly used extracellular matrix (ECM) materials. We designed a novel drug-loaded membrane by integrating the biological matrix (BM) composed of UBM and SIS composites with Resolvin D1 (RvD1), an endogenous pro-resolving lipid mediator, using the lyophilization process. This membrane is referred to as BRL, an acronym for BM-RvD1-Lyophilization. <b>Methods</b>: In this study, the physicochemical properties of the membranes were characterized. Fluorescence staining and the CCK8 assay kit were utilized to assess biocompatibility. To evaluate the inflammatory resolution properties and osteogenic ability of osteoblasts, real-time quantitative PCR and ELISA were conducted. <b>Results</b>: BRL exhibited a more pronounced three-dimensional pore structure, demonstrating excellent physicochemical properties and enabling the slow release of RvD1. This approach improved the viability of MG63 osteoblast-like cells, reduced LPS-induced inflammation, and upregulated osteogenesis-related genes significantly. <b>Conclusions</b>: By integrating inflammation control capabilities into tissue regeneration materials, BRL effectively regulates the tissue regeneration microenvironment, thereby enhancing regeneration efficiency and positioning itself as an exceptional candidate for future tissue regeneration membranes. |
