A Modular Perfusion Bioreactor Platform for Simulating Bone Regeneration and Fracture Healing: Integrating Mechanical Loading and Dual Perfusion for Advanced In Vitro Models

open access: yesAdvanced Healthcare Materials, EarlyView.
A modular bioreactor platform was developed in order to replicate bone homeostasis and pathology, thereby integrating mechanical loading, dynamic perfusion, and a 3D‐printed microfluidic chamber. With precise control of environmental parameters and dual perfusion for composite tissue models, the system enhances physiological relevance for studying bone

Preparation of Bifunctional Orthosilicophosphate MgO‐CaO‐ZnO‐P2O5‐SiO2 Glasses: in vitro Evaluation of Antibacterial Activity and Osteoblast Gene Expression Behavior

open access: yesAdvanced Healthcare Materials, EarlyView.
Bifunctional ZnO‐containing orthosilicophosphate glasses (SPGs) composed mainly of orthotetrahedral groups with the unique glass network structure without long‐chain units are prepared via melt‐quenching. The glasses exhibit excellent antibacterial activity and upregulate the expression of osteogenic markers by releasing inorganic ions.

A study of stress-free living bone and its application to space flight [PDF]

open access: yes
Observations of animals and human subjects in weightless space flight (Skylab and COSMOS) document altered bone metabolism. Bone metabolism is affected by a number of local and systemic factors.

Borate‐Ion‐Stimulated Macrophages Promote Osteogenic Differentiation of Mesenchymal Stem Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
The immune responses of mouse macrophages stimulated by borate ions promote the osteogenic differentiation and mineralization of mouse bone marrow–derived mesenchymal stem cells in an ion‐dose‐dependent manner by providing cytokines, including BMP‐2.

Beyond Bioactive Glass Composition: Using Morphology to Improve in Vitro and in Vivo Performance

open access: yesAdvanced Healthcare Materials, EarlyView.
Bioactive glasses can easily be shaped into granules, spheres, discs, fibers, or three‐dimensional scaffolds. The resulting morphology not only affects handling properties; it has a direct influence on various glass properties, including results of acellular immersion experiments or in vitro studies with cells or bacteria, but also on in vivo ...
