Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

open access: yesAdvanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

Ultra‐High Friction and Adhesion in Hydrogel Layer Driven by Wet‐to‐Dry Transition Dynamics

open access: yesAdvanced Science, EarlyView.
This work reveals a critical wet‐to‐dry transition in polyacrylamide hydrogel layers that induces volumetric shrinkage, resulting in enhanced interfacial contact and dramatically increased friction and adhesion. Leveraging this transition enables strong, reversible gripping on diverse surfaces, offering new insights for hydrogel‐based gripping ...

A Methodology for Deciphering the Transmembrane Resistance Variability of Supported Lipid Bilayers

open access: yesAdvanced Science, EarlyView.
This work shows that transmembrane resistance variability, due to lipid packing defects, can be quantified by analysing the dielectric properties of Supported Lipid Bilayers. The proposed methodology provides an analytical tool for optimizing SLB design with improved stability and functionality for bioelectronic and biomimetic applications. Abstract In

De Novo Gene Transcription of Connexin Mediates Cytoplasmic Fluid Exchange and Flocking Transitions in Physiological and Cancerous Epithelial Systems

open access: yesAdvanced Science, EarlyView.
EGF‐induced de novo transcription of connexins Cx26 and Cx31 promotes flocking behavior that fluidizes epithelia and enables coordinated collective migration. Connexin‐driven cytoplasmic exchange mechanistically links growth‐factor signaling to invasive dynamics.

Hyperviscous Diabetic Bone Marrow Niche Impairs BMSCs Osteogenesis via TRPV2‐Mediated Cytoskeletal‐Nuclear Mechanotransduction

open access: yesAdvanced Science, EarlyView.
Diabetic bone marrow exhibits pathological ECM hyperviscosity that activates TRPV2‐mediated Ca2⁺ influx, leading to perinuclear F‐actin disassembly, nuclear deformation, and chromatin condensation. This cytoskeletal‐nuclear decoupling suppresses osteogenic differentiation of BMSCs.
