Special Issue Information

Dear Colleagues,

The treatment and regeneration of large bone defects in the skeleton are complex, pose significant clinical challenges to surgeons and scientists, and impose a tremendous burden on healthcare systems worldwide. Even though bone tissue possesses the unique and intrinsic ability to heal, large bone defects have a limited capacity for spontaneous repair and often experience a poor long-term recovery. Despite innovations in surgical techniques, current clinical strategies for bone defect regeneration demonstrate significant limitations and drawbacks, including donor-site morbidity, the risk of infection, poor anatomical match, insufficient bone volume, higher costs, bone graft resorption, and rejection. In recent decades, advances in computer-assisted planning, three-dimensional (3D) printing technology, and bone tissue engineering (BTE) have offered promising novel treatment alternatives by employing biocompatible scaffold materials, autologous mesenchymal stem cells, and growth factors. Furthermore, the complex signaling cascade of the native immune system plays a crucial role in determining the efficacy and viability of the tissue-engineered implant. It forms an essential component of the BTE strategy. These approaches have provided a new platform for basic and translational research, and have exhibited promising results with regard to large bone regeneration that might profoundly improve patients’ function, form, and quality of life. Thus, 3D printing and BTE strategies are exciting, sustainable, personalized, and minimally invasive alternatives to bone harvesting techniques, and are therefore poised to significantly impact clinical outcomes.

This Special Issue aims to compile the recent advances in bone tissue engineering and their scientific and clinical applications. We welcome original research articles and comprehensive reviews that address the following topics: preclinical research; clinical trials; advances in biomaterials for bone tissue engineering; 3D printing and bioprinting technologies; and scaffold–immune system interactions.

Acquired cranial defects are a prevalent condition in neurosurgery and call for cranioplasty, where the missing or defective cranium is replaced by an implant. Nevertheless, the biomaterials in current clinical applications are hardly exempt from long-term safety and comfort concerns. An appealing solution is regenerative cranioplasty, where biomaterials with/without cells and bioactive molecules are applied to induce the regeneration of the cranium and ultimately repair the cranial defects. This review examines the current state of research, development, and translational application of regenerative cranioplasty biomaterials and discusses the efforts required in future research. The first section briefly introduced the regenerative capacity of the cranium, including the spontaneous bone regeneration bioactivities and the presence of pluripotent skeletal stem cells in the cranial suture. Then, three major types of biomaterials for regenerative cranioplasty, namely the calcium phosphate/titanium (CaP/Ti) composites, mineralised collagen, and 3D-printed polycaprolactone (PCL) composites, are reviewed for their composition, material properties, and findings from clinical trials. The third part discusses perspectives on future research and development of regenerative cranioplasty biomaterials, with a considerable portion based on issues identified in clinical trials. This review aims to facilitate the development of biomaterials that ultimately contribute to a safer and more effective healing of cranial defects. Full article
