Controlled Release of Human Dental Pulp Stem Cell‐Derived Exosomes from Hydrogels Attenuates Temporomandibular Joint Osteoarthritis

Advanced Healthcare Materials, EarlyView.
Exosomes can reduce tissue damage in temporomandibular joint osteoarthritis (TMJOA), but rapid clearance limits their efficacy. This study encapsulates exosomes in hyaluronic acid hydrogels for controlled release. In a rat model, hydrogel‐encapsulated exosomes outperform free exosomes in preserving bone integrity and reducing tissue destruction ...

Soft Pneumatic Device Designed to Mimic the Periosteal Environment for Regulating the Fate of Mesenchymal Stem Cells

Advanced Healthcare Materials, EarlyView.
This study presents a custom‐made soft pneumatic device (SPD) that mimics complex mechanical forces and fluid flow to enhance in vitro cell differentiation. It shows that low mechanotransduction promotes MSC differentiation into osteoprogenitor cells, while high mechanotransduction causes structural disruptions and cell detachment, providing new ...

Systematic Comparison of Commercial Uranyl‐Alternative Stains for Negative‐ and Positive‐Staining Transmission Electron Microscopy of Organic Specimens

Advanced Healthcare Materials, EarlyView.
Negative‐ and positive‐staining TEM is essential for rapid nanometer‐resolution characterization of organic specimens ranging from nanoparticles to cells. Uranyl salts are widely used negative‐/positive‐stains but are radioactive and highly toxic to users and the environment.
