Special Issue Information

Dear Colleagues,

We are delighted to be able to invite you to submit a manuscript to the forthcoming Special Issue of the International Journal of Molecular Sciences (IF: 5.6), entitled “The Application of Biomaterials in Bone Tissue Repair and Regeneration”.

This Special Issue is dedicated to an in-depth exploration of the potential applications inherent in mineralized tissue substitutes within the realms of both medicine and dentistry. The primary is to present a meticulous examination of the utilization of bone substitute materials to facilitate the natural emulation of the intricate bone cellular system, with a concerted effort to enhance our comprehension of the underlying bony nanostructure. Particular emphasis is placed on the judicious employment of synthetic biomaterials as bone substitutes, with a specific focus on novel methodologies involving nanomaterials and their rigorous assessment for clinical efficacy. Encompassing a wide array of subjects, including the characterization and application of bone substitute materials, biocompatibility assessment, physicochemical properties, materials in endodontic surgery, and the mechanical and biocompatible properties of CAD/CAM restorative materials, this Issue is poised to make substantial contributions to the scientific discourse surrounding advancements in the application of mineralized tissue substitutes across diverse domains.

This Issue focuses on advancing our understanding of biomaterial applications in the intricate process of bone tissue repair and regeneration. Submitted papers for this Special Issue are expected to present results that delve into molecular-level findings. Emphasis will be placed on exploring the intricate molecular mechanisms involved in the interaction between biomaterials and bone tissues, aiming to contribute valuable insights to the field of bone regeneration research.

Abstract

Bone tumors, particularly osteosarcoma, are prevalent among children and adolescents. This ailment has emerged as the second most frequent cause of cancer-related mortality in adolescents. Conventional treatment methods comprise extensive surgical resection, radiotherapy, and chemotherapy. Consequently, the management of bone tumors and bone regeneration poses significant clinical challenges. Photothermal tumor therapy has attracted considerable attention owing to its minimal invasiveness and high selectivity. However, key challenges have limited its widespread clinical use. Enhancing the tumor specificity of photosensitizers through targeting or localized activation holds potential for better outcomes with fewer adverse effects. Combinations with chemotherapies or immunotherapies also present avenues for improvement. In this review, we provide an overview of the most recent strategies aimed at overcoming the limitations of photothermal therapy (PTT), along with current research directions in the context of bone tumors, including (1) target strategies, (2) photothermal therapy combined with multiple therapies (immunotherapies, chemotherapies, and chemodynamic therapies, magnetic, and photodynamic therapies), and (3) bifunctional scaffolds for photothermal therapy and bone regeneration. We delve into the pros and cons of these combination methods and explore current research focal points. Lastly, we address the challenges and prospects of photothermal combination therapy.

An Overview on the Big Players in Bone Tissue Engineering: Biomaterials, Scaffolds and Cells

by Maria Pia Ferraz

Abstract

Presently, millions worldwide suffer from degenerative and inflammatory bone and joint issues, comprising roughly half of chronic ailments in those over 50, leading to prolonged discomfort and physical limitations. These conditions become more prevalent with age and lifestyle factors, escalating due to the growing elderly populace. Addressing these challenges often entails surgical interventions utilizing implants or bone grafts, though these treatments may entail complications such as pain and tissue death at donor sites for grafts, along with immune rejection. To surmount these challenges, tissue engineering has emerged as a promising avenue for bone injury repair and reconstruction. It involves the use of different biomaterials and the development of three-dimensional porous matrices and scaffolds, alongside osteoprogenitor cells and growth factors to stimulate natural tissue regeneration. This review compiles methodologies that can be used to develop biomaterials that are important in bone tissue replacement and regeneration. Biomaterials for orthopedic implants, several scaffold types and production methods, as well as techniques to assess biomaterials’ suitability for human use—both in laboratory settings and within living organisms—are discussed. Even though researchers have had some success, there is still room for improvements in their processing techniques, especially the ones that make scaffolds mechanically stronger without weakening their biological characteristics. Bone tissue engineering is therefore a promising area due to the rise in bone-related injuries. Full article
