Vitamin D Binding Protein, a Ligand of Integrin beta 1, Motivates Both Tumor Cells and Schwann Cells to Promote Perineural Invasion in Pancreatic Ductal Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
Group‐specific component protein (GC) promotes perineural invasion (PNI) in pancreatic ductal adenocarcinoma (PDAC) by activating Schwann cell dedifferentiation and by enhancing tumor–Schwann cell chemoattraction, independently of vitamin D transport. Integrin β1 (ITGB1) functions as a GC receptor in both cancer cells and Schwann cells.

An Injectable Zwitterionic Hydrogels with Multiple Intermolecular Interactions for Effective Prevention of Abdominal Adhesions

open access: yesAdvanced Science, EarlyView.
An injectable PSA‐ZnO through multiple intermolecular including hydrogen bonds and electrostatic interactions for effectively prevents abdominal adhesions. The PSA‐ZnO hydrogel demonstrates superior wound healing promotion (≥ 95%) and more effective inhibition of scar formation compared to the commercial 3M dressing (≈80%), and prevents post‐operative ...

Targeting Fibrotic Scarring by Mechanoregulation of Il11ra1+/Itga11+ Fibroblast Patterning Promotes Axon Growth after Spinal Cord Injury

open access: yesAdvanced Science, EarlyView.
This study demonstrates that a hydrogel with mechanical properties matching the spinal cord directs fibroblast alignment, reshaping fibrotic scars into parallel matrices. A specific fibroblast subset mediates extracellular matrix remodeling through mechanotransduction, promoting axonal regeneration and neural reconnections, revealing potential ...

MUC15 Ectodomain Architecture Regulates Integrin Clustering to Control Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
This study uncovers a size‐dependent adhesion paradigm, demonstrating that the glycocalyx protein MUC15 suppresses pancreatic cancer progression by attenuating integrin activation, focal adhesion assembly, and YAP mechanotransduction. Integrating computational modeling and experimental validation, the work reveals a mechanical mechanism by which MUC15 ...

Electrosensitive Heterogeneous Short Fibers via Acousto‐Electric Coupling for Sequential Bone Regeneration in Infectious Defects

open access: yesAdvanced Science, EarlyView.
Electrosensitive heterogeneous short fibers can accurately respond to ultrasonic field regulation through the synergistic interaction of piezoelectric and conductive dual elements. At an ultrasound intensity of 1.5 W cm−2, it can effectively activate bacterial peroxisome and necrotic apoptotic pathway and promote bacterial apoptosis.

Dual‐Pedicle Tissue‐Engineered Trachea Promotes Biomimetic Cartilaginous Framework, Vascularization, and Epithelial Lining for Long‐Segment Tracheal Reconstruction

open access: yesAdvanced Science, EarlyView.
Overcoming the limitations of conventional grafts, a biomimetic trachea with two independent vascular pedicles enables rapid integration and sustained patency. This approach markedly improves survival rates, restores the epithelial barrier, and promotes regenerative pathways, presenting a transformative paradigm for clinical application.

Long‐Term Stable Subdural Recordings Enabled by Fibrosis‐Resistant Hydrogel‐Integrated µECoG Arrays

open access: yesAdvanced Science, EarlyView.
An adhesive hydrogel‐integrated micro‐electrocorticography (aGel‐µECoG) array is developed to ensure stable neural recordings by minimizing neuroinflammation and fibrosis during implantation. The hydrogel serves as a biological and mechanical bridge, enabling bioadhesive, reversible, anti‐fibrotic integration with brain tissue.

Micro/Nanorobots for Combating Brain Disorders: Challenges, Advances, and Perspectives

open access: yesAdvanced Science, EarlyView.
Micro/nanorobots (MNRs) offer a transformative approach for precision therapy in brain disorders. By overcoming biological barriers and enabling controlled propulsion, targeted delivery, and real‐time imaging/tracking, MNRs pave the way toward effective, minimally invasive treatments. This review outlines the interplay between brain disease challenges,
