Micro‐Organ Chip Deciphers Tumor‐Derived G‐CSF as Remote Commander of Lung Pre‐Metastatic Niche via VEGFA‐KDR Cascade

open access: yesAdvanced Science, EarlyView.
Breast cancer reprograms the lung into a receptive pre‐metastatic niche via a novel G‐CSF–VEGFA–KDR signaling axis. Using a micro‐organ chip that enables contact‐independent coculture, this study uncovers how tumor‐secreted G‐CSF activates lung capillary KDR to drive angiogenesis and prime the soil for metastasis—without direct tumor contact.

Migrasomes in Ischemic Stroke: Molecular Landscape and Pathophysiological Impact

open access: yesAdvanced Science, EarlyView.
Multi‐omics profiling of stroke patients exposes systemic molecular fingerprints of immune activation, oxidative stress and metabolic collapse. Complement and coagulation cascade, and cholesterol metabolism emerge as shared functional hallmarks of plasma migrasomes in stroke patients and migrasomes isolated from experimental stroke mice.

Cascade‐Responsive MXene@Cu‐MOF Heterostructure Integrates Antioxidant Activity, Infection Control, and Vascularization for Tracheal Repair

open access: yesAdvanced Science, EarlyView.
A cascade‐responsive MXene@Cu‐MOF/GelMA hydrogel is engineered as a “skeleton–backpack” platform for extensive tracheal repair. The MXene framework scavenges postoperative ROS and converts NIR light into mild hyperthermia, while the Cu‐MOF component provides pH/NIR‐responsive Cu2+ dosing for infection control, angiogenesis, and chondrogenesis.

Versatile DNA Hydrogel‐Mediated Delivery of Ginsenoside‐Encapsulated Small Extracellular Vesicles to Boost Diabetic Wound Repair

open access: yesAdvanced Science, EarlyView.
This study presents a DNA hydrogel‐mediated delivery system, in which ginsenoside (GS) molecules are incorporated into small extracellular vesicles (sEV) secreted by mesenchymal stem cells (MSCs) and the formed complexes are then anchored in DNA hydrogels via aptamer‐CD63 affinity as “GS/sEV@DNAgels”, to improve diabetic wound repair.

Quantification of Single‐Cell Cysteine Using an Electrochemical Nanosensor for Predicting Tumor Disulfidptosis Susceptibility

open access: yesAdvanced Science, EarlyView.
Cysteine attracts interest due to its unique electrochemical activity and emerging relationship with disulfidptosis. This study develops a new electrochemical nanosensor, which represents the first of its kind capable of detecting intracellular cysteine for various types of tumor cells and primary tumor cells in mice to evaluate disulfidptosis ...
