Antioxidant and Anti‐Senescence Polyvinyl Alcohol‐Gallic Acid Supramolecular Hydrogels for Stem Cell Culture

open access: yesAdvanced Healthcare Materials, EarlyView.
The PVA‐GA hydrogel is formed through hydrogen bonding between PVA hydroxyl groups and GA galloyl units, enabling sustainable GA release and its extended biological activity. The hydrogel scavenges ROS to reduce oxidative stress, preventing mitochondrial damage from excessive ROS, mitigating hADSC senescence, and preserving VEGF secretion, offering a ...

Bioprinted Micro‐Clots for Kinetic Analysis of Endothelial Cell‐Mediated Fibrinolysis

open access: yesAdvanced Healthcare Materials, Volume 14, Issue 7, March 14, 2025.
This paper describes the development of a microscale model that quantifies the breakdown of fibrin by endothelial cells. The small size scale of this engineered system enables fibrin breakdown to be observed without the addition of external activators. This system could help in identifying compounds which both promote and hinder thrombosis.

Bioengineering a Patient‐Derived Vascularized Lung Tumor‐on‐Chip Model to Decipher Immunomodulation by the Endothelium

open access: yesAdvanced Healthcare Materials, EarlyView.
Most in vitro cancer models lack cellular diversity, functional complexity, and clinical relevance. This work highlights the generation of an innovative dynamic tetraculture with autologous patient‐derived cells within a vascularized tumor‐on‐chip, as well as the recapitulation of endothelial anergy features induced by the tumor microenvironment ...

Mechanically and Chemically Defined PEG Hydrogels Improve Reproducibility in Human Cardioid Development

open access: yesAdvanced Healthcare Materials, EarlyView.
Synthetic matrix metalloproteinase (MMP)‐degradable polyethylene glycol (PEG)‐based hydrogels are developed to investigate the influence of mechanical and biochemical cues on cardioid development. Matrix stiffness and cell adhesion motifs significantly regulate cardioid formation, chamber morphogenesis, contractile function, and cardioid transcriptome.
