Global Gene Expression Analysis Identifies Age-Related Differences in Knee Joint Transcriptome during the Development of Post-Traumatic Osteoarthritis in Mice. [PDF]
Aging and injury are two major risk factors for osteoarthritis (OA). Yet, very little is known about how aging and injury interact and contribute to OA pathogenesis.

The properties of bioengineered chondrocyte sheets for cartilage regeneration
Background Although the clinical results of autologous chondrocyte implantation for articular cartilage defects have recently improved as a result of advanced techniques based on tissue engineering procedures, problems with cell handling and scaffold ...

The role of the chondrocyte in osteoarthritis [PDF]
Osteoarthritis (OA) is a slowly progressive degenerative disease characterized by gradual loss of articular cartilage. Since the OA lesion is often localized to weight-bearing cartilage or to sites of trauma, repetitive mechanical injury has been proposed as the critical signal for the initiation and progression of OA. It is now generally accepted that

Potassium channels in articular chondrocytes [PDF]
Chondrocytes are the resident cells of cartilage, which synthesize and maintain the extracellular matrix. The range of known potassium channels expressed by these unique cells is continually increasing. Since chondrocytes are non-excitable, and do not need to be repolarized following action potentials, the function of potassium channels in these cells ...

Immunosuppressive Cytokine‐Tethered Hydrogel for Treating Rheumatoid Arthritis
An injectable hydrogel is developed by chemically tethering IL‐4, an immunosuppressive cytokine, to a hyaluronic acid‐based backbone. The hydrogel reduces joint friction and exerts immunomodulatory effects. In a rheumatoid arthritis (RA) mouse model, it reduced inflammation, preserved cartilage, and promoted anti‐inflammatory immune responses.

mTORC1 regulates PTHrP to coordinate chondrocyte growth, proliferation and differentiation
Precise coordination of cell growth, proliferation and differentiation is essential for the development of multicellular organisms. Here, we report that although the mechanistic target of rapamycin complex 1 (mTORC1) activity is required for chondrocyte ...

Chondrocyte Heterogeneity; It Is the Time to Update the Understanding of Cartilage Histology [PDF]
Chondrocytes were described as one cell populations in most cartilage literature. Two different chondrocyte populations; dark and light, were described in the articular cartilage and a third population, adipochondrocytes, was described in the elastic cartilage.

Linking Cellular and Mechanical Processes in Articular Cartilage Lesion Formation: A Mathematical Model [PDF]
A severe application of stress on articular cartilage can initiate a cascade of biochemical reactions that can lead to the development of osteoarthritis. We constructed a multiscale mathematical model of the process with three components: cellular, chemical, and mechanical.

c-Maf Transcription Factor Regulates ADAMTS-12 Expression in Human Chondrogenic Cells. [PDF]
ObjectiveADAMTS (a disintegrin and metalloproteinase with thrombospondin type-1 motif) zinc metalloproteinases are important during the synthesis and breakdown of cartilage extracellular matrix.
