Novel Vascular‐Adaptive Liquid Metal Microspheres Enable Visualized Arterial Embolization Therapy

Advanced Science, EarlyView.
We present drug‐loaded liquid metal microspheres (X‐MEN) as a novel agent for image‐guided arterial embolization. With inherent radiopacity and superior deformability, X‐MEN enables real‐time monitoring and conforms tightly to irregular vessels. This approach ensures precise, long‐lasting embolization without recanalization, addressing critical ...

Cockroach‐Derived Leucokinin VIII Peptide Accelerates Diabetic Skin Wound Healing by Enhancing Keratinocyte Filopodia Formation

Advanced Science, EarlyView.
This study identifies the cockroach‐derived peptide leucokinin VIII as a potent accelerator of diabetic wound healing. By activating the FAK‐ACTG1 axis, the peptide drives keratinocyte migration and filopodia formation. Delivered via a developed PLGA‐PEG‐PLGA thermosensitive hydrogel for sustained release, this approach significantly hastens wound ...

Development‐based In Vivo Bioreactor Strategy for Challenging Senescent Bone Reconstruction

Advanced Science, EarlyView.
We present a development‐based in vivo bioreactor strategy to generate rejuvenated bone grafts (vBR‐Bone) within aged hosts. By enclosing vBR‐Bone fragments within an asymmetric biomimetic periosteum, segmental femoral defects in aged mice were successfully repaired within 6 weeks. Mechanistically, the multifactors of vBR‐Bone reconstitute a remodeling
