A Triboelectric‐Hydrogel System for Mechano‐Metabolic Re‐Coupling in Skin Expansion: Recharging From Energy Crisis

Advanced Healthcare Materials, EarlyView.
Progressive skin expansion creates an energy crisis that compromises regenerative capacity. A self‐powered triboelectric‐hydrogel system (TP‐PAM/G) re‐couples mechanical loading with cellular metabolism by combining motion‐generated electrical stimulation and stress redistribution.

Hybrid Biofabrication of a Hierarchically Organized Periosteum‐Inspired In Vitro Platform

Advanced Healthcare Materials, EarlyView.
A hybrid biofabrication strategy integrates melt electrowriting with extrusion‐based 3D bioprinting to create a hierarchically organized periosteum‐inspired in vitro platform. Spatially defined osteogenic, fibrous, and endothelial cell‐containing compartments support long‐term culture, osteogenic maturation, and CD31+ endothelial cell organization ...

Artemisinin‐Loaded Core‐Shell Microspheres Modulate Histone Lactylation to Remodel the Microenvironment for Cartilage Protection in Rheumatoid Arthritis

Advanced Healthcare Materials, EarlyView.
ART@PLGA@GH‐A microspheres are developed via microfluidic technology for intra‐articular delivery of artemisinin. The system remodels rheumatoid arthritis microenvironments by regulating metabolic and inflammatory disorders, reducing lactate‐driven histone lactylation and cellular senescence, while restoring cartilage homeostasis and protecting joint ...
