Mesenchymal stem cells (MSCs) are known to have the potential for articular cartilage regeneration, and are suggested for the treatment of osteoarthritis (OA). Here, we investigated whether intra-articular injection of xenogeneic human adipose-derived mesenchymal progenitor cells (haMPCs) promoted articular cartilage repair in rabbit OA model and engrafted into rabbit articular cartilage. The h...

INTRODUCTION: Since partial defects in articular cartilage do not heal spontaneously, whereas injuries that penetrate the subchondral bone undergo some repair [1], we have begun to consider the development of tissue engineered osteochondral constructs consisting of a hybrid scaffold of chondrocyte-seeded hydrogel and devitalized trabecular bone; such a scaffold may improve cartilage repair and ...

Damage and degeneration of articular joints is a major healthcare concern, due to the association of joint disease with ageing, the current strong demographic changes in the proportion of elderly in the population, and the increased incidence of trauma in a sports-active younger population. These joints are biomechanical organs that transmit load between bones in our skeleton, and the articular...

Defects of load-bearing connective tissues such as articular cartilage, often result from trauma, degenerative or age-related disease. Osteoarthritis (OA) presents a major clinical challenge to clinicians due to the limited inherent repair capacity of articular cartilage. Articular cartilage defects are increasingly common among the elderly population causing pain, reduced joint function and si...

OBJECTIVE Avocado and soya unsaponifiables (ASU) have been reported to exert beneficial effects in the treatment of periodontal and osteoarticular diseases. They are supposed to stimulate deposition and repair of extracellular matrix components, but the mechanisms underlying their action are not well understood. In view of the repair potential of osteoarthritic (OA) cartilage and the role that ...

OBJECTIVE The ability to fully regenerate lost limbs has made the axolotl salamander (Ambystoma mexicanum) a valuable model for studies of tissue regeneration. The current experiments investigate the ability of these vertebrates to repair large articular cartilage defects and restore normal hyaline cartilage and joint structure independent of limb amputation. METHODS Full-thickness articular ...

Diseases in articular cartilages have affected millions of people globally. Although the biochemical and cellular composition of articular cartilages is relatively simple, there is a limitation in the self-repair ability of the cartilage. Therefore, developing strategies for cartilage repair is very important. Here, we report on a new liquid resin preparation process of water-based polyurethane...

Clinical and laboratory research aimed at biological approaches to cartilage repair are currently in high demand due to the poor regenerative capacity of articular cartilage in the setting of a diseased articular environment. Platelet-rich plasma (PRP) takes advantage of supraphysiological concentrations of platelets and their growth factors harbored in α-granules, which together attempt to ret...

Articular cartilage provides a vital function in the homeostasis of the joint environment. It possesses unique mechanical properties, allowing for the maintenance of almost frictionless motion over a lifetime. However, cartilage is vulnerable to traumatic injury and due to its poor vascularity and inability to access mesenchymal stem cells, unable to facilitate a satisfactory healing response. ...
