Backgrounds: Osteoarthritis (OA) significantly impacts the elderly, leading to disability and decreased quality of life. While hyaluronic acid (HA) and chondroitin sulfate (CS) are recognized for their therapeutic potential in OA, their effects on extracellular matrix (ECM) degradation are not well understood. This study investigates the impact of HA and CS, individually and combined, on ECM degradation in OA and the underlying mechanisms.

Articular cartilage and osteochondral defect repair and regeneration presents significant challenges to the field of tissue engineering (TE). TE and regenerative medicine strategies utilizing natural and synthetic-based engineered scaffolds have shown potential for repair, however, they face limitations in replicating the intricate native microenvironment and structure to achieve optimal regenerative capacity and functional recovery. Herein, we report the development of a cartilage extracellular matrix (ECM) as a printable biomaterial for tissue regeneration.

Aim: To explore the role of the hub gene Transforming Growth Factor Beta Induced (TGFBI) in Intervertebral disc degeneration (IDD) pathogenesis and its regulatory relationship with Membrane Associated Ring-CH-Type Finger 8 (MARCHF8).
Background: IDD is a prevalent musculoskeletal disorder leading to spinal pathology. Despite its ubiquity and impact, effective therapeutic strategies remain to be explored.

Osteoarthritis (OA) is a multi-factorial degenerative joint disease with unclear pathogenesis. Conservative treatments, primarily aimed at pain relief, fail to halt disease progression. Metabolic syndrome has recently been implicated in OA pathogenesis, underscoring the need for novel therapeutic strategies.

Osteoarthritis (OA) is currently the most common degenerative joint disease in China and even worldwide and is the leading cause of disability in the elderly population. So far, due to an insufficient understanding of the pathogenesis and etiology of the disease, there is still no effective targeted treatment for early OA. Pro-inflammatory cytokine interleukin-1 is an important inflammatory mediator secreted in early OA, and IL-1β plays a crucial role in the pathogenesis of OA, affecting chondrocytes and the extracellular matrix of CARTILAGE.
