Engineered Cyanobacteria‐Hydrogel Microecological System for Oxygen Reprogramming Synergizes Immunomodulation With Anabolism in Osteoarthritis Therapy

Advanced Science, EarlyView.
An injectable cyanobacteria‐laden hydrogel enables light‐dependent oxygen metabolism engineering for osteoarthritis therapy. Photosynthetic oxygen release under red light irradiation suppresses synovial inflammation via HIF‐1α inhibition and M2 macrophage polarization, while respiratory oxygen consumption in darkness stabilizes chondrocyte HIF‐1α to ...

TBBPA exposure causes cartilage cell damage in both in vitro and in vivo models

Ecotoxicology and Environmental Safety
Tetrabromobisphenol A (TBBPA) is a widely used flame retardant. TBBPA is a persistent pollutant that is difficult to degrade and causes sustained pollution to the environment.

Dual‐Gene Edited Extracellular Vesicles Remodel the Redox Homeostasis to Inhibit Ferroptosis in Intervertebral Disc Degeneration

Advanced Science, EarlyView.
ABSTRACT Intervertebral disc degeneration (IDD) is driven by ferroptosis of nucleus pulposus cells (NPCs) as a core pathological mechanism. Nucleus pulposus progenitor cells (NPPCs), exhibiting stem cell‐like properties, yield extracellular vesicles (PEVs) with high affinity for NPCs and enable targeted phenotypic regulation.

The growth plate sparing effects of the selective glucocorticoid receptor modulator, AL-438 [PDF]

, 2007
Long-term use of glucocorticoids (GC) can cause growth retardation in children due to their actions on growth plate chondrocytes. AL-438, a non-steroidal anti-inflammatory agent that acts through the glucocorticoid receptor (GR) retains full anti ...

Matrix Stiffness Orchestrates Mesenchymal Stem Cell Lineage Commitment Toward Osteogenesis and Adipogenesis Through the PIEZO1/SP1/STC2 Axis

Advanced Science, EarlyView.
Matrix stiffness directs mesenchymal stem cell lineage commitment through PIEZO1‐dependent activation of the SP1/STC2 pathway. Stiff matrices favor osteogenesis and suppress adipogenesis, whereas the loss of PIEZO1 function impairs early bone formation. STC2 retains lineage‐regulatory activity even when PIEZO1 is inactive.

Unravelling the Distinct Phenotype and Mechanosensitive Properties of Different Tendon Cell Populations

Advanced Science, EarlyView.
Tendon interfascicular and fascicular matrix cells are isolated and cultured, revealing distinct phenotypes and mechanosensitive responses. Interfascicular matrix cells exhibit marked stiffness‐dependent phenotypic plasticity, whereas fascicular matrix cells remain comparatively stable.

ACSL4‐Dependent Lysosomal Lipid Peroxidation Links WTAP‐Mediated m6A Modification to Intervertebral Disc Degeneration

Advanced Science, EarlyView.
IL‐1β upregulates the protein level of WTAP, which promotes the m6A modification of ACSL4 mRNA in an IGF2BP2‐dependent manner, thereby enhancing its stability. The increased ACSL4 drives lipid peroxidation, leading to lysosomal membrane permeabilization (LMP) and impaired mitophagy, which collectively accelerate intervertebral disc degeneration (IVDD).

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

JCI 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 ...

Mechanoelectrical transduction in chondrocytes

Clinical and Experimental Pharmacology and Physiology, 2018
SummaryCartilage tissue lines the joints of mammals, helping to lubricate joint movement and distribute mechanical loads. This tissue is comprised of isolated cells known as chondrocytes which are embedded in an extracellular matrix. Chondrocytes produce and maintain the cartilage by sensing and responding to changing mechanical loads. Mechanosensitive
