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

Advanced 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. ABSTRACT Articular

β1-Integrin-Mediated Uptake of Chondrocyte Extracellular Vesicles Regulates Chondrocyte Homeostasis. [PDF]

Osteoarthritis (OA) is the most prevalent age-related degenerative disorder, which severely reduces the quality of life of those affected. Whilst management strategies exist, no cures are currently available.

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

Advanced 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 ...

Cell density alters matrix accumulation in two distinct fractions and the mechanical integrity of alginate-chondrocyte constructs

, 2005
Chondrocyte density in articular cartilage is known to change with the development and growth of the tissue and may play an important role in the formation of a functional extracellular matrix (ECM).

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

Advanced 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 ...

Mechanical Activation of Piezo1 Drives Osteoarthritis Through Kdm5c‐Mediated Epigenetic Silencing

Advanced Science, EarlyView.
Excessive mechanical stress activates Piezo1, triggering Ca2+‐dependent cytoskeletal forces that deform the nucleus and reduce H3K4me3. Kdm5c demethylates H3K4me3 at Col2a1 and Runx3 promoters. Kdm5c knockout rescues degradation. Repurposed telmisartan directly inhibits Kdm5c, blocking this axis and showing disease‐modifying efficacy in mouse OA models

Anti‐inflammatory and osteogenic effects of transcutaneous electrical nerve stimulation in knee osteoarthritis rats via the regulation of the intestinal microbiota

Animal Models and Experimental Medicine, EarlyView.
Transcutaneous electrical nerve stimulation (TENS) improved knee osteoarthritis (KOA) in rats by regulating interleukin‐1β (IL‐1β), IL‐6, and IL‐8 expressions and the bone morphogenetic protein 2 (BMP‐2)/transforming growth factor β (TGF‐β) signaling pathway.

Liposomal Delivery of L‐2‐Hydroxyglutarate for Targeting Epigenetic Dysregulation in Osteoarthritis

Advanced NanoBiomed Research, EarlyView.
Osteoarthritis involves cartilage degeneration, inflammation, and epigenetic dysregulation. A liposomal formulation of the TET1 inhibitor L‐2‐hydroxyglutarate to overcome rapid joint clearance was developed. The formulation showed good physicochemical properties, reduced inflammatory and catabolic gene expression in chondrocytes, and alleviated ...
