Progress in bone tissue engineering biomaterials: Development, challenges, and prospects
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

: In healthy cartilage, chondrocytes maintain an expression of collagens and proteoglycans and are sensitive to growth factors and cytokines that either enhance or reduce type II collagen synthesis. In osteoarthritis, pro-inflammatory cytokines, such as

Human platelet lysate acts as a metabolic primer for hNPCs, enhancing fatty acid oxidation to drive proliferation while preserving phenotype. This enables construction of high‐quality, large‐size macromasses without necrotic defects, demonstrating exceptional efficacy in repairing degenerated discs in situ and providing a novel paradigm for ...

The sEH inhibitor TPPU upregulates endothelial HIF‐1α, activating the NOTCH signalling pathway between endothelial cells and mesenchymal stem cells. This promotes the differentiation and formation of FABP5+ septoclasts, enhances their participation in endochondral ossification, and ultimately improves longitudinal bone growth and fracture healing ...

Excessive mechanical stress induces nucleus pulposus cell pyroptosis and intervertebral disc degeneration. Itgb1 inhibits MNAT1‐mediated ubiquitination and degradation of Vimentin. Vimentin alleviates excessive mechanical stress‐induced nucleus pulposus cell pyroptosis and intervertebral disc degeneration through PINK1‐Parkin‐dependent mitophagy ...

The structure and function of cartilage proteoglycans [PDF]
Cartilage contains a variety of proteoglycans that are essential for its normal function. These include aggrecan, decorin, biglycan, fibromodulin and lumican. Each proteoglycan serves several functions that are determined by both its core protein and its

Background/Objective: Asporin is associated with osteoarthritis and lumbar disk degeneration. Previous studies in chondrocytes showed that asporin can bind to transforming growth factor-β1 (TGF-β1) and downregulate matrix biosynthesis.

Combating ageing beyond the cell: Emerging roles of extracellular proteostasis
Ageing challenges the body's ability to maintain a stable and functional proteome, leading to protein damage and aggregation both inside and outside cells. This review focuses on the less well understood mechanisms of extracellular protein quality control and how they become disrupted in ageing, particularly in neurodegenerative diseases.
