A Biomimetic Nanoparticle System Intercepts and Degrades Thrombospondin‐1 to Restore Vascular Homeostasis After Ischemic Injury

Advanced Science, EarlyView.
TAX2‐NPs capture extracellular TSP‐1 in the injured liver and promote its macrophage‐mediated autophagic degradation. This process blocks TSP‐1/CD47 signaling, restores VEGFR2‐AKT activity, preserves endothelial function, and mitigates hepatic ischemia‐reperfusion injury.

Brown Adipocyte Sheets Alleviate Myocardial Ischemia–Reperfusion Injury Through NRG4–ErbB4–Dependent Ferroptosis Inhibition

Advanced Science, EarlyView.
Brown adipocyte sheets are engineered to protect the heart against myocardial ischemia–reperfusion injury by restraining ferroptosis. Upon transplantation onto the cardiac surface, they improve cardiac function, limit infarction and fibrosis, and enhance angiogenesis.

Dual‐Stage Microneedle Patch With Lipid Droplet‐Mediated ‘Capture‐Kill’ and Sustained Release for Enhanced Wound Healing

Advanced Science, EarlyView.
We report a lipid‐droplet‐engineered, gallium‐loaded sonodynamic therapeutic platform (LDTG) incorporated into a bilayer microneedle (MN) patch co‐delivering all‐trans retinoic acid (ATRA), termed LDTG A‐MNs, for synergistic antibacterial therapy and accelerated wound repair.

A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

Advanced Science, EarlyView.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.
