Bone defects resulting from trauma, surgery, and congenital, infectious, or oncological diseases are a functional and aesthetic burden for patients. Bone regeneration is a demanding procedure, involving a spectrum of molecular processes and requiring the use of various scaffolds and substances, often yielding an unsatisfactory result. Recently, the new collagen sponge and its structural derivatives manufactured from European carp () were introduced and patented. Due to its fish origin, the novel scaffold poses no risk of allergic reactions or transfer of zoonoses and additionally shows superior biocompatibility, mechanical stability, adjustable degradation rate, and porosity. In this review, we focus on the basic principles of bone regeneration and describe the characteristics of an "ideal" bone scaffold focusing on guided bone regeneration. Moreover, we suggest several possible applications of this novel material in bone regeneration processes, thus opening new horizons for further research.

This systematic review and meta-analysis aimed to evaluate the long-term clinical outcomes of regenerative procedures compared with access flap surgery for the treatment of intrabony defects, with a minimum follow-up period of 5 years. A systematic review protocol following PRISMA guidelines was conducted. Both electronic and manual searches were conducted to identify randomized clinical trials (RCTs) on regenerative treatment of deep intrabony defects (≥3 mm) with a follow-up of at least 5 years.

Background: Charcot foot is a debilitating complication of peripheral neuropathy and is primarily associated with diabetes, leading to structural damage, ulceration, and osteomyelitis. Pulsed electromagnetic field (PEMF) therapy is a promising treatment modality for wound healing and bone metabolism.
Objective: To evaluate the efficacy of PEMF therapy in promoting bone growth and ulcer healing in patients with Charcot foot ulcers.

Objective: Diabetic foot ulcer (DFU) is a common and serious complication of diabetes, often leading to infection, amputation and poor quality of life. Bone marrow mesenchymal stem cells (BMSCs) have shown promise in treating chronic wounds, but their therapeutic efficacy is limited due to poor survival and low regenerative activity. Low-intensity pulsed ultrasound (LIUS), a non-invasive physical modality, has been shown to enhance the biological behavior of BMSCs.

Osteochondral defects caused by trauma, obesity, tumors, and degenerative osteoarthropathies severely impair patients' quality of life. Multilayer tissue engineering scaffolds offer promising strategies for osteochondral repair by enhancing structural biomimicry. In this study, a triple-layer GelMA-alginate-based osteochondral scaffold (TCOS) was fabricated using an enhanced multi-axis, multi-process, multi-material 3D bioprinting system (MAPM-BPS).

Angiotensin II (Ang II) releases inflammatory mediators from several cell types. The objective of this study was to investigate the potential of Ang II to induce mRNA expression of inflammatory mediators in primary cultured fibroblast-like cells isolated from gingival and periodontal ligament tissues. A synergistic effect of co-treatment with Ang II and Interleukin-1β (IL1β) on the mRNA expression of inflammatory mediators was explored.
