Ascorbic Acid Modulates Collagen Properties in Glucocorticoid‐Induced Osteoporotic Bone: Insights into Chemical, Mechanical, and Biological Regulation

open access: yesAdvanced Healthcare Materials, EarlyView.
Osteoporosis from long‐term glucocorticoid (GIOP) use elevates susceptibility to fracture. This study shows GCs impair ascorbic acid (AA) metabolism in osteoblasts, collagen synthesis and extracellular matrix integrity. AA enhanced collagen biochemical and mechanical properties and restored osteoblast and endothelial function. These findings underscore

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.

Geometry‐Guided Osteogenesis in Bone‐on‐a‐Chip Systems Using Triply Periodic Minimal Surface Scaffolds

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a bone‐on‐a‐chip platform incorporating TPMS scaffolds to study geometry‐dependent osteogenesis under dynamic flow. By tuning pore shape and solidity, it precisely controls mechanical cues, revealing how topological features and shear stress affect osteogenic differentiation and matrix formation.

Magnetic Bioprinting and Actuation of Stretchable Muscle Tissue

open access: yesAdvanced Healthcare Materials, EarlyView.
Human and murine myoblasts labeled with iron oxide nanoparticles are magnetically bioprinted into wrench‐shaped tissues, which are then anchored between two magnetic needles. Mechanical stretching of these tissues enhances both their maturation and functional performance. Abstract Engineering tissues with precise, long‐lasting shapes and the capability
