Bone‐Derived dECM Hydrogels Support Tunable Microenvironments for In Vitro Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
A tunable methacrylated decellularized bone matrix hydrogel (dECM‐MA) is developed to support 3D culture of human osteoblasts. The hydrogel preserves bone‐specific ECM cues and allows precise control over mechanical properties. This system provides a customizable platform for studying osteogenic differentiation and modeling bone tissue environments for

A Novel Core–Shell Hydrogel 3D Model for Studying Macrophage Mechanosensing and Foreign Body Giant Cell Formation

Advanced Healthcare Materials, EarlyView.
The foreign body response (FBR) to biomaterials is primarily driven by macrophages, which often fuse into destructive foreign body giant cells (FBGCs). To address the limited understanding of FBGC formation, a novel microscale core–shell hydrogel 3D model is developed using heterogeneous alginate‐collagen microcapsules with varying stiffness, offering ...
