Geometrically Tunable Scaffold‐Free Muscle Bioconstructs for Treating Volumetric Muscle Loss

Advanced Healthcare Materials, EarlyView.
Volumetric muscle loss is associated with traumatic muscle resulting in permanent functional impairment. Mold‐based, scaffold‐free, high‐density muscle tissue bioconstructs are developed in customizable geometric shapes and sizes. The transplanted rectangular solid‐shaped muscle bioconstructs improved muscle force recovery and tissue regeneration in ...

Geometrical Designs in Volumetric Bioprinting to Study Cellular Behaviors in Engineered Constructs

Advanced Healthcare Materials, EarlyView.
Curvature and spatial confinement guide cell behavior in volumetrically printed 3D constructs. Endothelial cells align and spread along specific geometries, while metastatic osteosarcoma cells proliferate independently of structural cues. Label‐free holographic microscopy captures real‐time, long‐term cell–material interactions, highlighting Gel‐PEG's ...

Mesenchymal Stem Cell‐Derived Apoptotic Micro‐Vesicles Repaired Sciatic Nerve Defect by Regulating Early Inflammatory Microenvironment and Promoting Angiogenesis

Advanced Healthcare Materials, EarlyView.
HUCMSC‐Apo‐mvs enhance peripheral nerve repair by modulating the inflammatory microenvironment (IME), primarily through coordinated actions on three functional cells. They recruit macrophages and promote their polarization from pro‐inflammatory M1 to anti‐inflammatory M2 phenotypes, increasing secretion of IL‐10 and VEGF.

Triazine‐Trione Thermosets with High Processability for Scaffold Applications in Bone Tissue Engineering

Advanced Healthcare Materials, EarlyView.
Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

Characterization of an Injectable Poly(vinyl alcohol)‐gelatin Hydrogel for Growth Factor Delivery in an Orthopedic Application

Advanced Healthcare Materials, EarlyView.
This work introduces photo‐crosslinkable tyraminated poly(vinyl alcohol)‐gelatin (PVA‐GT) hydrogels as tunable injectable platforms for tissue engineering and growth factor delivery applications. This schematic illustrates the two developed hydrogel formulations and the experimental workflow used to evaluate their physico‐chemical properties in vitro ...

Dual‐Functional Polyphosphoesters for Gene Delivery: Synergistic Effects of Guanidinium and Hydrophobic Side Chains in Degradable Polymers

Advanced Healthcare Materials, EarlyView.
This study presents guanidinium‐ and indole‐functionalized polyphosphoesters as degradable, non‐viral gene delivery vectors. Through precise tuning of charge density and hydrophobicity, these polymers form stable polyplexes with low toxicity. Remarkably, minor structural changes yield up to 200‐fold differences in transfection efficiency, highlighting ...

Isolation Defines Identity: Functional Consequences of Extracellular Vesicle Purification Strategies

Advanced Healthcare Materials, EarlyView.
Four extracellular vesicle purification strategies are compared using ovarian‐cancer ascites and ES‐2 cell supernatants. A novel workflow links purification to function by combining particle‐normalized proteomics with matched cell‐free and cell‐based assays.

Start, Stop, Rewind, Repeat—Cyclic Exposure of Adipose Stromal Cells‐derived Cartilage Organoids to Chondrogenic and Proliferative Cues to Achieve Scaled‐up and Customizable Bone Formation by Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
This study exploits the plasticity of ASCs‐derived cartilage organoids which generate a perichondrial layer of MSCs when exposed to cyclic chondrogenic/proliferative cues. Using these organoids as building blocks, we develop (i) Phalange Shaped Tissue Engineered Cartilage (Pa‐TECs), recapitulating endochondral ossification suitable for the treatment of
