Matrix Viscoelasticity Orchestrates Osteogenesis via Mechanotransduction Mediated Metabolic Switch in Macrophages

Advanced Healthcare Materials, EarlyView.
Fast‐relaxation viscoelastic hydrogel triggers a metabolic shift in macrophages, favoring oxidative phosphorylation (OXPHOS) over glycolysis via vasodilator‐stimulated phosphoprotein (VASP) / hypoxia‐inducible factor 1 alpha (HIF1α) signaling meditated mechanotransdution, thereby enhancing their capacity to recruit mesenchymal stem cells (MSCs) and ...

A Dual‐Layer Hydrogel Barrier Integrating Bio‐Adhesive and Anti‐Adhesive Properties Prevents Postoperative Abdominal Adhesions

Advanced Healthcare Materials, EarlyView.
A new dual‐layer hydrogel barrier for preventing postoperative abdominal adhesions is developed. The inner layer, consisting of polyethyleneimine (PEI) and thioctic acid (TA), enhanced adhesion to moist tissues. The outer layer combines zwitterionic, thermoresponsive hyaluronic acid with anti‐inflammatory epigallocatechin gallate (EGCG) and forms a ...

Biofunctionalization of ADA‐GEL Hydrogels Based on the Degree of Cross‐Linking and Polymer Concentration Improves Angiogenesis

Advanced Healthcare Materials, EarlyView.
The biocompatibility of alginate dialdehyde (ADA) and gelatin (GEL) hydrogels cross‐linked with human transglutaminase (hTG) is demonstrated in vivo with a high degree of stability and angiogenic potential. The additional enzymatic cross‐linker hTG and the increased concentration improve stability and angiogenic potential. The X‐ray microscopy (XRM) is

Self‐Healing Hydrogel Dressing with Solubilized Flavonoids for Whole Layer Regeneration of Diabetic Wound

Advanced Healthcare Materials, EarlyView.
High glucose‐ and acid‐responsive hydrogel with dynamic covalent bond solubilized with flavonoids (Gel‐Flavonoids) is designed for diabetic wound healing. The Gel‐Flavonoids adapt to irregular wound shapes and release antioxidants in high‐glucose environments, effectively reducing reactive oxygen species.
