Recent progress in cartilage lubrication [PDF]

open access: yesarXiv, 2023
Healthy articular cartilage, covering the ends of bones in major joints such as hips and knees, presents the most efficiently-lubricated surface known in nature, with friction coefficients as low as 0.001 up to physiologically high pressures. Such low friction is indeed essential for its well being.

Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

Discerning the spatio-temporal disease patterns of surgically induced OA mouse models [PDF]

open access: yes, 2019
Osteoarthritis (OA) is the most common cause of disability in ageing societies, with no effective therapies available to date. Two preclinical models are widely used to validate novel OA interventions (MCL-MM and DMM).

Are Paralysed Chondrocytes Really Dying? [PDF]

open access: yesarXiv, 2017
The aims of the current study were to establish a system of culture for induction of paralysed chondrocytes and to investigate if these cells are really dying. Chondrocytes were isolated from the growth cartilage of fetal equines, centrifuged and cultured as pellets in either 10% fetal calf serum or 10% horse serum for 28 days and processed for light ...

Time-of-flight secondary ion mass spectrometry-based molecular distribution distinguishing healthy and osteoarthritic human cartilage [PDF]

open access: yes, 2013
Osteoarthritis (OA) is a pathology that ultimately causes joint destruction. The cartilage is one of the principal affected tissues. Alterations in the lipid mediators and an imbalance in the metabolism of cells that form the cartilage (chondrocytes) have been described as contributors to the OA development.

Effects of mechanical stress on chondrocyte phenotype and chondrocyte extracellular matrix expression [PDF]

open access: yesScientific Reports, 2016
AbstractMechanical factors play a key role in regulating the development of cartilage degradation in osteoarthritis. This study aimed to identify the influence of mechanical stress in cartilage and chondrocytes. To explore the effects of mechanical stress on cartilage morphology, we observed cartilages in different regions by histological and ...

Pyrophosphate‐Containing Calcium Phosphates Negatively Impact Heterotopic Bone Quality

open access: yesAdvanced Healthcare Materials, EarlyView.
The role of calcium pyrophosphate (Ca‐PP) in heterotopic bone formation and material degradation is investigated using calcium phosphate (CaP) compositions with varying Ca‐PP content. Results show that Ca‐PP does not impede heterotopic bone formation, minimally affects CaP degradation at non‐osseous sites, and increases phagocytosis.

CCL2 induces articular chondrocyte MMP expression through ERK and p38 signaling pathways

open access: yesOsteoarthritis and Cartilage Open, 2021
Objective: In previous studies, we determined an association between increased serum and articular cartilage levels of CCL2 with osteoarthritis (OA) progression, cartilage damage and increased MMP13 in cartilage.

BMSC-Derived Exosomes Ameliorate Osteoarthritis by Inhibiting Pyroptosis of Cartilage via Delivering miR-326 Targeting HDAC3 and STAT1//NF-κB p65 to Chondrocytes

open access: yesMediators of Inflammation, 2021
Background. In the past decade, mesenchymal stem cells (MSCs) have been widely used for the treatment of osteoarthritis (OA), and noncoding RNAs in exosomes may play a major role. Aim.
