Visible Light Induced DLP‐Printed Oxygen‐Releasing TPMS Scaffolds Mitigate Early Hypoxia in Bone Defects

open access: yesAdvanced Healthcare Materials, EarlyView.
Visible light‐induced digital light processing 3D printed Primitive‐triply periodic minimal surface hydrogels embed CaO2–Si core–shell nanoparticles to deliver short‐term oxygen during the avascular window. The scaffolds maintain cytocompatibility, elevate osteopontin in vitro, and enhance calvarial defect repair in vivo without toxicity.

A Heparin‐Functionalized Scaffold with HB‐EGF Immobilization for Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
In this study, a heparin‐functionalized scaffold is designed for bio‐mimicking growth factors reservoir function of extracellular matrix. Due to the presence of heparin‐binding domain, heparin‐binding epidermal growth factor‐like growth factor (HB‐EGF) is effectively and spatially captured by heparin‐functionalized scaffold.
