Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

Advanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Encoded Cell‐Material Interactions to Reroute Cytokine Signaling for Regenerative Medicine

Advanced Healthcare Materials, EarlyView.
We present native MATRIX (Material Activated To Regulate Inducible gene eXpression), a co‐engineered material‐cell platform. Surfaces functionalized with antibodies for endogenous soluble ligands (e.g., IL‐1β or IL‐6) capture and immobilize ligands for presentation to a cognate, engineered synthetic Notch receptor, releasing a transcription factor (TF)

A Fully Defined GelMA‐Based Matrix Allows Fine Tuning of Tissue‐Relevant Biomechanical and Biochemical Cues for Organoid Culture

Advanced Healthcare Materials, EarlyView.
A fully defined GelMA‐based ECM platform integrates tunable tissue‐relevant stiffness with laminin–entactin biochemical supplementation to support mouse small intestinal organoid growth. Coordinated control of mechanical and biochemical cues promotes robust proliferation, budding morphogenesis, differentiation, and passaging, providing a reproducible ...

Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

Advanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...

Mechanotransduction of Magnetically Applied Forces Leads to Mechanical Stiffening of Platelet‐Rich Plugs

Advanced Healthcare Materials, EarlyView.
A microfluidic device with magnetic microposts was used to assess platelet mechanobiology. The oscillatory actuation of posts with embedded iron particles was dampened by the dynamic stiffening of the platelet‐rich plugs. This stiffening process increased with applied load, but inhibiting platelet activation (ASA) or myosin contractility (blebbistatin)
