Introduction

Skeletal muscle injuries, whether caused by trauma, disease, or age-related degeneration, present significant challenges in both clinical management and functional recovery. The intrinsic regenerative capacity of skeletal muscle is often insufficient to fully restore structure and function following severe injury, leading to impaired mobility and decreased quality of life for affected individuals. In recent years, biomaterial-based approaches have emerged as promising strategies to enhance skeletal muscle regeneration by providing structural support, delivering bioactive factors, and creating conducive microenvironments for tissue repair [1]. This introduction aims to provide an overview of the role of biomaterials in skeletal muscle regeneration, highlighting their importance in addressing the limitations of natural healing processes and advancing the field of regenerative medicine. Biomaterials offer unique advantages in promoting muscle repair by serving as scaffolds to support cell infiltration, differentiation, and tissue integration, as well as carriers for controlled release of growth factors and other signaling molecules crucial for myogenesis and angiogenesis [2, 3].

Description

Biomaterials have emerged as valuable tools in the realm of skeletal muscle regeneration, offering innovative solutions to address the challenges associated with muscle injuries and disorders. Skeletal muscle possesses a limited regenerative capacity, and severe injuries often result in fibrosis and functional deficits. Biomaterials designed for skeletal muscle regeneration aim to enhance the natural healing process by providing structural support, promoting cellular interactions, and delivering bioactive molecules crucial for tissue repair and regeneration. One of the key roles of biomaterials in skeletal muscle regeneration is to serve as scaffolds that mimic the native Extracellular Matrix (ECM) [4]. These biomaterial scaffolds provide a three-dimensional framework for cell infiltration, proliferation, and differentiation, facilitating the formation of new muscle tissue. Natural polymers such as collagen, fibrin, and alginate, as well as synthetic polymers like polyesters and polycaprolactone, have been utilized to create biomaterial scaffolds with tailored properties, including mechanical strength, degradation kinetics, and bioactivity [5].

In addition to providing structural support, biomaterials act as carriers for bioactive factors that regulate muscle regeneration processes. Growth factors, cytokines, and extracellular vesicles play crucial roles in promoting myogenic differentiation, angiogenesis, and tissue remodeling. Biomaterial-based delivery systems enable controlled release of these bioactive molecules, ensuring their sustained presence at the injury site and enhancing their therapeutic efficacy [6].

Furthermore, biomaterials serve as platforms for cell-based therapies aimed at augmenting skeletal muscle regeneration. Myogenic progenitor cells, Mesenchymal Stem Cells (MSCs), and Induced Pluripotent Stem Cells (iPSCs) can be seeded onto biomaterial scaffolds and guided to differentiate into myocytes [7, 8]. These cells contribute to tissue repair by integrating into existing muscle fibers, secreting trophic factors, and modulating the local microenvironment to promote regeneration [9]. Preclinical studies using animal models have demonstrated the efficacy of biomaterial-based approaches in promoting skeletal muscle regeneration and functional recovery. These studies have provided valuable insights into the mechanisms underlying biomaterial-mediated tissue healing and guided the development of clinically relevant therapies [10].

Conclusion

Despite the progress made, challenges remain in optimizing biomaterial properties, enhancing cellular interactions, and translating these approaches into clinical practice. Regulatory considerations and scalability issues also need to be addressed to ensure the safe and effective implementation of biomaterials in skeletal muscle regeneration therapies. In conclusion, biomaterials play a crucial role in advancing the field of skeletal muscle regeneration by providing scaffolds for tissue engineering, delivering bioactive molecules, and supporting cell-based therapies. With continued research and innovation, biomaterial-based approaches hold great promise for improving outcomes for patients with muscle injuries and disorders, ultimately enhancing their quality of life and functional mobility.
