A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

open access: yesAdvanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration.

Urocortin protects chondrocytes from acute trauma in articular cartilage

open access: yes, 2017
Purpose: Single injurious mechanical impact to joints, as seen in sports injury, is known to be associated with a high risk of later development of osteoarthritis (OA).

In Vitro Evaluation of Vancomycin-Induced Toxicity in Human Primary Knee Chondrocytes

open access: yes, 2023
Septic arthritis as a complication of orthopaedic joint surgery can have catastrophic outcomes for patients. To minimise infection risk associated with elective orthopaedics, topical vancomycin during surgery has become increasingly common.

Cyclic mechanical load causes global translational arrest in articular chondrocytes: a process which is partially dependent upon PKR phosphorylation [PDF]

open access: yesEuropean Cells & Materials, 2011
he cellular mechanisms by which articular cartilage responds to load are poorly understood, but such responses may involve regulation at the level of protein translation rather than synthesis of mRNA.

Mastication‐Induced Electrical Stimulation Activates Prg4+ Chondroprogenitors for Osteoarthritis Therapy

open access: yesAdvanced Science, EarlyView.
This study presents a ″trash‐to‐treasure″ strategy that converts harmful joint overloads into beneficial electrical cues. The biodegradable MagPie, by providing piezoelectrical stimulation and releasing Mg2+ during mastication, exerts synergistic pro‐regenerative and anti‐inflammatory effects on Prg4+ cells via the ECM‐mediated FAK‐PI3K‐Akt axis ...

Morphological properties of articular chondrocytes in various experimental and clinical conditions [PDF]

open access: yes, 2015
Previous work has suggested that there exists a relationship between chondrocyte morphology and matrix metabolism. Changes to chondrocyte morphology have been reported in human cartilage however it is unclear if these are involved in the degenerative ...

Hedgehog activation promotes osteogenic fates of growth plate resting zone chondrocytes through transient clonal competency

open access: yesJCI Insight
The resting zone of the postnatal growth plate is organized by slow-cycling chondrocytes expressing parathyroid hormone-related protein (PTHrP), which include a subgroup of skeletal stem cells that contribute to the formation of columnar chondrocytes ...

Mechanisms of chondrocyte apoptosis

open access: yesOsteoarthritis and Cartilage, 1999
This study addresses the occurrence and significance of chondrocyte apoptosis in the pathogenesis of cartilage destruction. Chondrocyte apoptosis can be induced in vitro by nitric oxide donors, but not by pro-inflammatory cytokines, such as IL-1 or TNF.

Lesion Site‐Targeted Microspheres Modulate Nav1.7‐Related Signaling for Osteoarthritis Treatment

open access: yesAdvanced Science, EarlyView.
Cartilage‐targeted carbamazepine‐loaded WYRGRL‐modified composite microspheres (CBZ/WCOM) anchor to exposed type II collagen in osteoarthritic lesions and release carbamazepine under acidic conditions. This bind‐then‐release platform modulates Nav1.7‐related sodium signaling, Na⁺/Ca²⁺ exchanger‐associated Ca2+ dynamics, and heat shock protein 70 ...

Cartilage tissue engineering: controlled release of growth factors. Effects of GDF-5, sexual steroid hormons and oxygen

open access: yes, 2007
Articular cartilage is likely a major candidate to be successfully regenerated by tissue engineering methods; first commercial products have already reached the market. However, to fully regenerate articular cartilage tissue, further optimization appears
