Bifunctional Surfaces With Immobilized Antibodies and Bioactive Peptides Mediate Selective Capture and Proliferation of Endothelial Colony‐Forming Cells

Advanced Healthcare Materials, EarlyView.
A tunable bifunctional surface is developed by combining Fc‐binding peptides and RGD motifs to present oriented antibodies alongside integrin‐mediated signaling. The platform selectively captures endothelial colony‐forming cells while promoting their adhesion and proliferation.

Piezoelectric Surface Charge and Dynamic Stimulation Synergize to Promote Cardiac Myoblast Alignment and Maturation

Advanced Healthcare Materials, EarlyView.
Surface polarization of PVDF films combined with mechanical stimulation generates piezoelectric electrical cues that modulate cardiomyoblast behaviour. Non‐poled and poled PVDF substrates provide distinct electroactive microenvironments influencing cell adhesion, proliferation, and differentiation.

Containerless-prepared bioactive glasses with mild alkalinity: Combining biocompatibility and bioactivity

Journal of Advanced Ceramics
Biomaterial-induced mild alkaline microenvironments can positively affect osteoblast activity, contributing to bone regeneration. However, the challenge associated with silicate bioactive glasses, including melt-derived 45S5 Bioglass (45S5-Glass) and sol–

Bioactive glass 45S5 from diatom biosilica

Journal of Science: Advanced Materials and Devices, 2017
A major draw-back to large scale production of bioactive glasses is the high cost of the standard silica precursor, usually tetraethyl orthosilicate (TEOS).

Bioactive glass and glass‐ceramic orbital implants

International Journal of Applied Ceramic Technology, 2019
Abstract This review focuses on the applications of bioactive glasses and glass‐ceramics in the field of orbital implants for ocular surgery. This use is relatively novel and less popular compared to the applications in orthopedics and dentistry for the repair of bone and teeth.

Extracellular Vesicles Modulation by an Adiponectin Receptor Agonist Provides Cardioprotection for Myocardial Ischemic Injury

Advanced Healthcare Materials, EarlyView.
This study demonstrates that ALY688, a drug mimicking the heart‐protective hormone adiponectin, reduces myocardial ischemia injury. ALY688 increases the production of extracellular vesicles, which carry protective cargo including adiponectin itself.

Bioactive SrO-SiO2 glass with well-ordered mesopores: Characterization, physiochemistry and biological properties [PDF]

, 2011
For a biomaterial to be considered suitable for bone repair it should ideally be both bioactive and have a capacity for controllable drug delivery; as such, mesoporous SiO2 glass has been proposed as a new class of bone regeneration material by virtue of

Physicochemical Reinforcement Unlocks Sterilization‐Stable Anisotropic Hydrogels for Cell‐Compatible Mock Arteries

Advanced Healthcare Materials, EarlyView.
ABSTRACT In vitro arterial models offer ethical and robust alternatives for vascular research but require cytocompatible materials that replicate physiological mechanics. Poly(vinyl alcohol) (PVA) hydrogels produced by directional freezing and salting‐out (PVA DFSO) are anisotropic yet lack stability for cell culture. Herein, methacrylated PVA (PVA‐MA)
