Combination of chondrocytes and chondrons improves extracellular matrix production to promote the repairs of defective knee cartilage in rabbits

open access: yesJournal of Orthopaedic Translation, 2021
Background: Chondrons are composed of chondrocytes and the surrounding pericellular matrix (PCM) and function to enhance chondrocyte-mediated cartilage tissue engineering.

Optimization of TGF-β1-transduced chondrocytes for cartilage regeneration in a 3D printed knee joint model.

open access: yesPLoS ONE, 2019
A cell therapy product of transforming growth factor (TGF)-β1-transduced chondrocytes has been commercialized to treat osteoarthritis of the knee via intra-articular injection.

Metaplasia of Chondrocytes into Osteoblasts

open access: yesFolia Biologica, 2006
Hypertrophic chondrocytes, commonly considered as terminal cells responsible for apoptotic elimination in endochondral osteogenesis, have the potential to switch their metabolic role and enter osteoblastic differentiation, based on histochemical, immunohistochemical, biochemical and cytological analysis.

In Vivo Chondrocyte Mechanics [PDF]

open access: yesBiophysical Journal, 2010
Mechanical loading of joints deforms articular cartilage cells, and that these cells provide the signals for maintaining cartilage health. Excessive loading of cartilage and cells leads to cartilage degeneration and osteoarthritis.Recently, we developed a novel in vivo testing system that allows for quantification of the mechano-biology of chondrocytes

Mechanical confinement regulates cartilage matrix formation by chondrocytes

open access: yesNature Materials, 2017
Cartilage tissue equivalents formed from hydrogels containing chondrocytes could provide a solution for replacing damaged cartilage. Previous approaches have often utilized elastic hydrogels.

SOX9 governs differentiation stage-specific gene expression in growth plate chondrocytes via direct concomitant transactivation and repression. [PDF]

open access: yesPLoS Genetics, 2011
Cartilage and endochondral bone development require SOX9 activity to regulate chondrogenesis, chondrocyte proliferation, and transition to a non-mitotic hypertrophic state.

The n-acetyl phenylalanine glucosamine derivative attenuates the inflammatory/catabolic environment in a chondrocyte-synoviocyte co-culture system [PDF]

open access: yes, 2019
Osteoarthritis (OA), the most prevalent degenerative joint disease, still lacks a true disease-modifying therapy. The involvement of the NF-κB pathway and its upstream activating kinases in OA pathogenesis has been recognized for many years.

Immunological Response against Allogeneic Chondrocytes Transplanted into Joint Surface Defects in Rats

open access: yesCell Transplantation, 1997
Rat chondrocytes isolated from the articular–epiphyseal cartilage complex were transplanted into defects prepared in articular cartilage and subchondral bone. Transplants were taken for examination after 3 and 8 wk.

Autophagy plays a protective role in advanced glycation end products- induced apoptosis of chondrocytes via regulation of tumor necrosis factor-α , nuclear factor-κ B and reactive oxygen species

open access: yesAsian Pacific Journal of Tropical Medicine, 2018
Objective: To study the adverse effects of advanced glycation end products (AGEs) on chondrocytes and the role of autophagy in this process. Methods: Chondrocytes were harvested from the human articular cartilage tissues in surgery.
