Erythropoietin‐Stimulated Macrophage‐Derived Extracellular Vesicles in Chitosan Hydrogel Rescue BMSCs Fate by Targeting EGFR to Alleviate Inflammatory Bone Loss in Periodontitis

open access: yesAdvanced Science, EarlyView.
A therapeutic strategy is proposed for periodontitis using extracellular vesicles derived from EPO‐stimulated macrophages (EPO‐EVs). This schema demonstrates how EPO‐EVs enhance the osteogenic activity of mBMSCs in an inflammatory environment by inhibiting EGFR.

Partial-to-Full Registration based on Gradient-SDF for Computer-Assisted Orthopedic Surgery [PDF]

open access: yesarXiv
In computer-assisted orthopedic surgery (CAOS), accurate pre-operative to intra-operative bone registration is an essential and critical requirement for providing navigational guidance. This registration process is challenging since the intra-operative 3D points are sparse, only partially overlapped with the pre-operative model, and disturbed by noise ...

3D‐Printed Titanium Trabecular Scaffolds with Sustained Release of Hypoxia‐Induced Exosomes for Dual‐Mimetic Bone Regeneration

open access: yesAdvanced Science, EarlyView.
This study presents 3D‐printed Ti‐6Al‐4V trabecular scaffolds combined with hypoxia‐induced exosomes encapsulated in PEGDA/GelMA microspheres for sustained release. The scaffolds mimic the structure of natural bone, while the exosome delivery system enhances osteogenesis and angiogenesis, significantly promoting bone regeneration and offering a ...

Engineered Stem Cell Clusters for Extracellular Vesicles‐Mediated Gene Delivery to Rejuvenate Chondrocytes and Facilitate Chondrogenesis in Osteoarthritis Therapy

open access: yesAdvanced Science, EarlyView.
BMSCmotif+miR874/MS system is designed as a gene delivery platform utilizing engineered bone marrow mesenchymal stem cell (BMSC)‐derived extracellular vesicles (EVs) for intercellular communication to achieve sustained delivery of miRNA‐874‐3p. Rejuvenation of chondrocytes and promotion of chondrogenesis are achieved by inhibition of the NF‐κB pathway,

Dissociation Between the Growing Opioid Demands and Drug Policy Directions Among the U.S. Older Adults with Degenerative Joint Diseases [PDF]

open access: yes, 2019
We aim to examine temporal trends of orthopedic operations and opioid-related hospital stays among seniors in the nation and states of Oregon and Washington where marijuana legalization was accepted earlier than any others.

Mechanical Load‐Induced Upregulation of Talin2 through Non‐Canonical Deubiquitination of OTUB1 Drives Facet Joint Osteoarthritis Pathogenesis

open access: yesAdvanced Science, EarlyView.
Facet joint osteoarthritis (FJOA), prevalent in the elderly, involves Talin2 upregulation promoting ECM degradation while suppressing synthesis. Mechanical load stabilizes Talin2 via OTUB1‐mediated non‐canonical deubiquitination, driving CCL2 expression that recruits immune cells, exacerbating inflammatory joint degeneration.
