Patient‐Derived 3D Bioprinted Cardiac Organoid Constructs Reveal Key Pathological Features of Duchenne Muscular Dystrophy

open access: yesAdvanced Healthcare Materials, EarlyView.
Patient‐derived cardiac organoids reveal key features of Duchenne muscular dystrophy cardiomyopathy, including apoptosis, oxidative stress, calcium handling defects, and mechanical remodeling. By integrating organoids into alginate–gelatin bioprinted constructs, disease phenotypes are organized into scalable 3D cardiac tissues displaying extracellular ...

A 3D Astrocyte Microenvironment Model Enables Rapid Ca2+‐Resolved Analysis and Therapeutic Modulation of Oxidative Neuroinflammation

open access: yesAdvanced Healthcare Materials, EarlyView.
This work presents ARC‐3D, a soft 3D model that recreates how brain support cells, called astrocytes, react to oxidative stress. The system visualizes rapid calcium changes and inflammatory signals, and shows how the drug KDS12025 can protect cells from damage. ARC‐3D offers a simple, reliable way to study early drivers of brain inflammation.

Amine‐Functionalized Chitosan/dECM Composite Promotes Cutaneous Regeneration and Hair Follicle Activation by Regulating Oxidative Stress and Inflammation

open access: yesAdvanced Healthcare Materials, EarlyView.
An amine‐functionalized chitosan and hydrolyzed dECM composite promotes cutaneous regeneration by modulating oxidative stress and inflammatory pathways. The material accelerates wound closure and stimulates hair follicle activation in UV‐damaged cutaneous tissue.

Isolation Defines Identity: Functional Consequences of Extracellular Vesicle Purification Strategies

open access: yesAdvanced 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.

A New 3D Colon on a Chip to Decipher the Influence of Mechanical Forces on the Physiological Cellular Ecosystem

open access: yesAdvanced Healthcare Materials, EarlyView.
To dissect how mechanical forces influence intestinal physiology, we developed a stretchable 3D colon‐on‐chip that integrates tunable topography, stiffness and peristalsis‐like motion within a physiologically relevant microenvironment. We showed that stretching is a dominant factor governing epithelial behavior, markedly enhancing proliferation and ...

Microwave‐Assisted Aqueous Synthesis of Gelatin‐Norbornene for Hydrogel Crosslinking and Bioprinting

open access: yesAdvanced Materials Technologies, EarlyView.
A microwave‐assisted reaction is utilized to synthesize gelatin‐norbornene (GelNB), achieving a high degree of norbornene functionalization while reducing the macromer's upper critical solution temperature. The resulting GelNB macromer has high solubility at room temperature, facilitating light‐based 3‐dimensional (3D) printing of thiol‐norbornene ...
