Engineering Extracellular Vesicle Production Through Magnetic Ion Channel Activation for Bone Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
Magnetic Ion Channel Activation (MICA) enables remote stimulation of mechanosensitive ion channels using functionalised magnetic nanoparticles, enhancing extracellular vesicle (EV) biogenesis is pre‐osteoblasts. MICA desrived EVs exhibit typical nano‐vesicular characteristics but display superior pro‐osteogeneic activity, promoting mesenchymal stem ...

Three‐Dimensional Ovary Model to Improve and Study Murine Follicle Growth

open access: yesAdvanced Healthcare Materials, EarlyView.
To develop new methods for fertility preservation in women, novel culture systems for small follicles need to be established. In this work, a poly(ethylene glycol) based scaffold, with appropriate mechanical and bioactive features to support mouse follicle and ovary cell growth is developed, and the formed cell‐follicle interactions are visualized ...

ETV2 Mediated Differentiation of Human Pluripotent Stem Cells Results in Functional Endothelial Cells for Engineering Advanced Vascularized Microphysiological Models

open access: yesAdvanced Healthcare Materials, EarlyView.
A robust method to generate functional human iPSC‐derived endothelial cells using inducible ETV2 expression. These cells self‐organize into stable, lumenized microvascular networks within microfluidic chips, surpassing conventional differentiation methods.

A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Design and Synthesis of Peptide‐Polyester Conjugates for Cell‐Mediated Scaffold Degradation

open access: yesAdvanced Healthcare Materials, EarlyView.
This work describes polycaprolactone (PCL)‐based biomaterials engineered to degrade in response to cell‐secreted proteases. A fast‐degrading peptide (Fast) sequence is integrated into a PCL conjugate backbone to produce a biomaterial that is selectively degraded by multiple cell types compared to its scrambled control (ScrFast).

Copolymers of Poly(Butylene Trans‐1,4‐Cyclohexanedicarboxylate)/Pripol as New Biomaterial Platform for Small Diameter Vascular Graft

open access: yesAdvanced Healthcare Materials, EarlyView.
Electrospun tubular scaffolds from novel PBCE‐based copolyesters and blends were designed as candidates for small‐diameter vascular grafts. They combine defect‐free architecture, blood‐compatible surfaces, and mechanical properties comparable to native vessels.

Diels‐Alder Click Chemistry as a Dynamic‐Covalent Crosslinking Method in Spheroid‐Encapsulating Hydrogels for Cartilage Engineering

open access: yesAdvanced Healthcare Materials, EarlyView.
This research shows the development of hydrogels with Diels‐Alder click chemistry for engineering cartilage‐like tissue. The hydrogels support cartilage spheroids which could be cultured for at least 28 days. Furthermore, the spheroids showed a tendency to fuse together into a more consistent construct, and produced important components needed for ...

Calcium Phosphate Mineralization

Connective Tissue Research, 1989
Although it is often assumed that the thermodynamically most stable hydroxyapatite is a suitable prototype for biological minerals, it is now generally accepted that other phases such as dicalcium phosphate dihydrate and octacalcium phosphate as well as defect apatites and carbonated apatites may participate.

Calcium Phosphate Transfection

Current Protocols in Neuroscience, 1997
AbstractThis unit presents two methods of calcium phosphate‐based eukaryotic cell transfection that can be used for both transient and stable transfections. In these protocols, plasmid DNA is introduced to monolayer cell cultures via a precipitate that adheres to the cell surface.

Calcium phosphate clusters

Biomaterials, 2001
The potential energy surfaces associated with [Ca3(PO4)2n clusters are analyzed in detail using ab initio calculations for n ranging from one to four. Considering separated clusters, energy criteria favor the so-called Posner's cluster Ca9(PO4)6, which is the core of the actual structural model of amorphous calcium phosphate.
