Electrospun P(VDF-TrFE)/ceria nanoparticle scaffolds for skeletal muscle regeneration
Volumetric muscle loss (VML) presents a significant clinical challenge due to the limited regenerative capacity of skeletal muscle. Piezoelectric scaffolds have shown promise in enhancing muscle repair by converting mechanical cues into bioelectric signals. In this study, we investigate the regenerative potential of electrospun scaffolds composed of poly(vinylidene fluoride-trifluoroethylene) [P(VDF-TrFE)] and polycaprolactone (PCL), with or without cerium dioxide nanoparticles (Ce NPs), in a VML mouse model. Hyaluronic acid functionalization was employed to improve scaffold biocompatibility. In vitro experiments confirmed the biocompatibility of these scaffolds, while in vivo assessments over eight weeks demonstrated significant efficacy in restoring muscle function. Compared with PCL-Ce scaffolds, mice implanted with piezoelectric scaffolds exhibited faster grip strength recovery, more mature muscle regeneration, a more hierarchical arrangement of muscle fibers, and increased fiber diameter. Additionally, the antioxidant properties of Ce NPs reduced adipocyte infiltration and excessive collagen deposition and were associated with enhanced angiogenesis. Grip strength measurements further highlighted the superior regenerative performance of P(VDF-TrFE) scaffolds combined with Ce NPs. Overall, these findings underscore the potential of piezoelectric scaffolds integrated with antioxidants in promoting structural and functional muscle regeneration following VML.
期刊介绍:
Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry.
The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
