Kinsenoside‐Loaded Microneedle Accelerates Diabetic Wound Healing by Reprogramming Macrophage Metabolism via Inhibiting IRE1α/XBP1 Signaling Axis

Advanced Science, EarlyView.
Gut metabolite trimethylamine N‐oxide accumulates in the diabetic wound area to amplify macrophage inflammation via enhancing glycolysis activities. Kinsenoside induces macrophage repolarization from M1 to M2 phenotype through inhibiting IRE1α/XBP1 pathway, followed by HIF‐1α‐glycolysis axis repression and mitophagy‐oxidative phosphorylation axis ...

Global existence of weak solutions to a cell migration and (de)differentiation model with double haptotaxis in the context of tissue regeneration [PDF]

arXiv
We study a model for the spread and (de)differentiation of mesenchymal stem cells and chondrocytes in a scaffold whose fibers are coated with hyaluron. The chondrocytes produce new extracellular matrix, which, together with hyaluron, serves as haptotactic cue for the stem cell migration.

Cartilage‐Penetrating Framework Nucleic Acid Nanoparticles Ameliorate Osteoarthritis by Promoting Drug Delivery and Chondrocyte Uptake

Advanced Science, EarlyView.
Based on the poor cartilage penetration of tFNA, a novel tFNA‐2WL with excellent cartilage permeability and perfect chondrocyte endocytosis properties is designed and fabricated. As a result, tFNA‐2WL has a nearly seven‐fold increase in the penetration depth into the cartilage, with the same excellent cell entry properties as tFNA.

Inhibition of Heat Shock Protein 90β by Catalpol: A Potential Therapeutic Approach for Alleviating Inflammation‐Induced Cartilage Injuries in Osteoarthritis

Advanced Science, EarlyView.
The schematic diagram delineates the chondroprotective effects of Ca‐bMSN in OA models. The upper portion of the diagram depicts the synthesis process of Ca‐bMSN. The lower section illustrates the post‐injection of Ca‐bMSN in joint cavity, catalpol released and subsequently mediates the reduction of oxidative stress, ECM catabolism, apoptosis, and ...

The role of mitochondrial quality control mechanisms in chondrocyte senescence

Experimental Gerontology
Chondrocytes are the exclusive cellular constituents of articular cartilage, and their functional status governs the health of the cartilage. The primary factor contributing to the deterioration of cartilage structure and function is chondrocyte ...

DNA Origami‐Based CD44‐Targeted Therapy Silences Stat3 Enhances Cartilage Regeneration and Alleviates Osteoarthritis Progression

Advanced Science, EarlyView.
This study develops a cartilage‐targeted DNA origami system (OCS) that protects and delivers si‐Stat3 to chondrocytes. OCS reduces MMP13 expression, enhances extracellular matrix stability, and lowers oxidative stress while improving cell survival. In vivo, OCS decreases cartilage degradation biomarkers and promotes tissue repair factors, demonstrating

A hybrid cellular automaton model of cartilage regeneration capturing the interactions between cellular dynamics and scaffold porosity [PDF]

arXiv, 2018
To accelerate the development of strategies for cartilage tissue engineering, models are necessary to study the interactions between cellular dynamics and scaffold (SC) porosity. In experiments, cells are seeded in a porous SC where over a month, the SC slowly degrades while cells divide and synthesize extracellular matrix (ECM) constituents. We use an

Functionalized Biomimetic Nanoparticles Targeting the IL‐10/IL‐10Rα/Glycolytic Axis in Synovial Macrophages Alleviate Cartilage Degeneration in Osteoarthritis

Advanced Science, EarlyView.
The MOF material UIO‐66‐NH2 is functionalized with DBCO groups on its surface, encapsulating NO‐prednisolone and conjugating it with azide‐modified IL‐10. Finally, the complex is extruded with MM to form biomimetic functional nanoparticles. Upon intra‐articular injection, MI@UN, enveloped by the MM, specifically targets synovial macrophages, is ...
