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.

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 ...

Mathematical Prediction for Geometry‐Mediated Cell 3D In‐Growth on Bone Tissue Engineering Scaffolds

open access: yesAdvanced Science, EarlyView.
This study identifies a fundamental pore size dependent pattern of three dimensional bone marrow derived mesenchymal stem cell (BMSC) infiltration within porous scaffolds, where small pores promote horizontal cellular bridging and large pores facilitate vertical migration.

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.

Rescuing Mitochondrial Dysfunction in Macrophages Prevents Osteonecrosis of the Jaw in Anti‐Resorptive Therapy

open access: yesAdvanced Science, EarlyView.
Schematic model showing the suggested mechanism that ZA induces classical activation of macrophages by impairing mitochondrial biofunction and inhibiting mitochondrial clearance to contribute to the pathological process of BRONJ. RAPA‐loaded nanoparticles ZDPR has shown potential in alleviating BRONJ lesions as well as treating osteoporosis or ...
