mTORC1 regulates PTHrP to coordinate chondrocyte growth, proliferation and differentiation

Nature Communications, 2016
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 ...

The role of the chondrocyte in osteoarthritis [PDF]

Arthritis & Rheumatism, 2000
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

Microphysiological Systems for Comorbidity Studies: Chronic Kidney Disease and Osteoarthritis

Advanced Healthcare Materials, EarlyView.
This review highlights the potential of organ‐on‐a‐chip systems for studying comorbidities, using chronic kidney disease (CKD) and osteoarthritis (OA) as examples. It summarizes recent advances in kidney‐on‐a‐chip and joint‐on‐a‐chip models and discusses their current and potential application in investigating CKD, OA, and CKD‐OA comorbidity, aiming to

Low-intensity pulsed ultrasound inhibits chondrocyte senescence by inhibiting PI3K/AKT/mTOR signaling

Brazilian Journal of Medical and Biological Research
Cellular senescence is an important cause of age-related degenerative diseases, including osteoarthritis (OA). Chondrocyte senescence is crucial in OA onset and progression.

Applications of Chondrocyte-Based Cartilage Engineering: An Overview

BioMed Research International, 2016
Chondrocytes are the exclusive cells residing in cartilage and maintain the functionality of cartilage tissue. Series of biocomponents such as different growth factors, cytokines, and transcriptional factors regulate the mesenchymal stem cells (MSCs ...

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

Advanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

An Organ‐on‐Chip Platform for Strain‐Controlled, Tissue‐Specific Compression of Cartilage and Mineralized Osteochondral Interface to Study Mechanical Overloading in Osteoarthritis

Advanced Healthcare Materials, EarlyView.
A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...

Induced superficial chondrocyte death reduces catabolic cartilage damage in murine posttraumatic osteoarthritis.

Journal of Clinical Investigation, 2016
Joints that have degenerated as a result of aging or injury contain dead chondrocytes and damaged cartilage. Some studies have suggested that chondrocyte death precedes cartilage damage, but how the loss of chondrocytes affects cartilage integrity is not
