FSTL1 Orchestrates Metabolic‐Epigenetic Crosstalk: Glycolysis‐Dependent H3K18 Lactylation Drives Cartilage Fibrosis in Osteoarthritis

open access: yesAdvanced Science, EarlyView.
FSTL1 promotes glycolysis during chondrocyte fibrosis by triggering the HIF‐1 signaling pathway, which causes lactate to accumulate. The buildup of lactate leads to changes in histone lysine lactylation, which in turn enhances the expression of genes associated with fibrosis.

Mechanical Stress Triggers Premature Senescence in Cardiac Fibroblasts

open access: yesAdvanced Science, EarlyView.
Cellular senescence contributes to disease burden in cardiovascular disease (CVD) and aging, highlighting the need to understand its induction. In primary cardiac fibroblasts, reduced strain and increased frequency, mimicking CVD, elicit a distinct senescent phenotype compared to oxidative stress.

Identification and Mechanisms of Osteocyte Subsets Involved in the Pathological Progression of Osteoporosis

open access: yesAdvanced Science, EarlyView.
Osteocyte heterogeneity in bone remains poorly understood. This study identifies six distinct osteocyte subsets in mice, revealing a key subpopulation (BHR‐Ocys) that drives bone loss in osteoporosis. BHR‐Ocys promote osteoclast‐mediated resorption via a novel Sema5a‐Plxna1 signaling axis.

Anti‐Swelling Hydrogel Combined With Nucleus Pulposus Cell Exosomes and Senolytic Drugs Efficiently Repair Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
In this study, a bifunctional anti‐swelling hydrogel system is developed, which encapsulated anti‐senescence drugs quercetin, dasatinib, nucleus pulposus‐derived exosomes (NP‐Exo) to clear senescent nucleus pulposus cells, regulate the inflammatory disc microenvironment, and enhance nucleus pulposus cells activity, ultimately promoting the repair of ...

Synovial Fluid‐derived Micrococcus Luteus G18 Exacerbates Osteoarthritis Progression by Promoting Chondrocyte Degradation via TLR2/JNK/AP‐1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
Traditionally considered sterile, the articular cavity is now recognized to harbor microbial communities influencing osteoarthritis (OA). Integrating 16S rRNA sequencing and culturomics, Micrococcus luteus is enriched in advanced OA. Notably, M. luteus G18 exacerbates cartilage degeneration via TLR2/JNK/AP‐1‐mediated ECM disruption, revealing intra ...

Dual‐Pedicle Tissue‐Engineered Trachea Promotes Biomimetic Cartilaginous Framework, Vascularization, and Epithelial Lining for Long‐Segment Tracheal Reconstruction

open access: yesAdvanced Science, EarlyView.
Overcoming the limitations of conventional grafts, a biomimetic trachea with two independent vascular pedicles enables rapid integration and sustained patency. This approach markedly improves survival rates, restores the epithelial barrier, and promotes regenerative pathways, presenting a transformative paradigm for clinical application.

Osteoclast‐Derived SLIT3 Mediates Osteoarthritis Pain and Degenerative Changes

open access: yesAdvanced Science, EarlyView.
In TMJ‐OA, osteoclasts play a significant role in promoting the growth of sensory nerves at the osteochondral interface. In early OA, TRAP+ osteoclast‐derived SLIT3 induces sensory nerve growth into the condylar cartilage. This nerve growth facilitates the development of pain associated with OA.
