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

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.

Platelet Lysate–Enriched Human Induced Pluripotent Stem Cell–Derived Chondrocyte Sheets for Bone Defect Repair via Endochondral Ossification

open access: yesAdvanced Healthcare Materials, EarlyView.
Human iPSC‐derived hypertrophic chondrocyte sheet promotes bone regeneration. Abstract Bone defects are a major clinical challenge, primarily owing to the limited self‐healing capacity of bones and the high risk of complications associated with conventional treatment strategies.

SiO2‐CaOCME/Poly(Tetrahydrofuran)/Poly(Caprolactone) 3D‐Printed Scaffolds Drive Human‐Bone Marrow Stromal Cell Osteogenic Differentiation

open access: yesAdvanced Healthcare Materials, EarlyView.
3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...

Gentamicin‐Loaded Carbonate Apatite with Dual Antibacterial and Osteogenic Functions for Combating Surgical Site Infections

open access: yesAdvanced Healthcare Materials, EarlyView.
A bone substitute with gentamicin physically precipitated onto the surface of carbonate apatite exhibits prompt drug release, high bactericidal activity, and osteogenic capacity. Efficient antibacterial activity mitigates early postoperative neutrophil accumulation, the status of which may serve as a potential parameter for evaluating the antibacterial

Triazine‐Trione Thermosets with High Processability for Scaffold Applications in Bone Tissue Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
Novel photo‐clickable triazine‐trione thermosets can be shaped and cured under mild conditions, including room and physiological temperatures. These materials are biocompatible and support osteogenic differentiation of bone marrow–derived mesenchymal stem cells on their surface.

HISTOLOGICAL AND HISTOCHEMICAL EVALUATION OF NORMOTENSIVE AND PREECLAMPTIC PLACENTAS

open access: yesInternational Journal of Health Services Research and Policy, 2019
The placenta plays a role in the pathophysiology of preeclampsia. Preeclampsia is more common in multifetal pregnancies than singleton pregnancies. In this study, we aimed to investigate the histopathology of normotensive and preeclamptic placentas and ...
