The β-catenin/TCF-4 pathway regulates the expression of OPN in human osteoarthritic chondrocytes

open access: yesJournal of Orthopaedic Surgery and Research, 2020
Background Cartilage destruction is the main characteristic of osteoarthritis (OA), and osteopontin (OPN) is elevated in OA articular cartilage; however, the reason for the increased OPN level is not determined.

Primary cilia disassembly down-regulates mechanosensitive hedgehog signalling: a feedback mechanism controlling ADAMTS-5 expression in chondrocytes [PDF]

open access: yes, 2014
SummaryObjectiveHedgehog signalling is mediated by the primary cilium and promotes cartilage degeneration in osteoarthritis. Primary cilia are influenced by pathological stimuli and cilia length and prevalence are increased in osteoarthritic cartilage ...

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.

Growth factors for clinical-scale expansion of human articular chondrocytes : Relevance for automated bioreactor systems [PDF]

open access: yes, 2007
The expansion of chondrocytes in automated bioreactors for clinical use requires that a relevant number of cells be generated, starting from variable initial seeding densities in one passage and using autologous serum.

Asporin expression is highly regulated in human chondrocytes [PDF]

open access: yesMolecular Medicine, Feinstein Institute for Medical Research, 2010, 17 (7-8), pp.816-23, 2015
A significant association between a polymorphism in the D repeat of the gene encoding asporin and osteoarthritis, the most frequent of articular diseases, has been recently reported. The goal of the present study was to investigate the expression of this new class I small leucine-rich proteoglycan (SLRP) in human articular chondrocytes.

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.

Modulation of transforming growth factor beta signalling pathway genes by transforming growth factor beta in human osteoarthritic chondrocytes: involvement of Sp1 in both early and late response cells to transforming growth factor beta [PDF]

open access: yesArthritis Research \& Therapy, 2010, 13 (1), pp.R23. \. \<10.1038/sj.onc.1204808\>, 2015
Transforming growth factor beta (TGF$\beta$) plays a central role in morphogenesis, growth, and cell differentiation. This cytokine is particularly important in cartilage where it regulates cell proliferation and extracellular matrix synthesis. While the action of TGF$\beta$ on chondrocyte metabolism has been extensively catalogued, the modulation of ...

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.

A novel culture system for modulating single cell geometry in 3D [PDF]

open access: yes, 2015
Dedifferentiation of chondrocytes during in vitro expansion remains an unsolved challenge for repairing serious articular cartilage defects. In this study, a novel culture system was developed to modulate single cell geometry in 3D and investigate its ...
