STIM1 mediates multiple signalling pathways in neuronal growth cones

, 2014
Calcium is an intracellular second messenger that is vital for normal neuronal function. The maintenance of calcium homeostasis is critical for healthy neuronal function, and disruption in calcium homeostasis has been implicated in diseases such as ...

Flash Assembloids: A Rapid Biofabrication of a Platform for Modeling Early Glioblastoma Invasion at the Glioblastoma–Brain Organoid Interfaces

Advanced Healthcare Materials, EarlyView.
This study presents a bioengineered assembloid (ASM) system combining glioblastoma (GBM) cells in oxidized alginate (OA) microgels with dorsal organoids (DOs). This model simulates brain tumor‐host interactions, revealing enhanced GBM invasion, altered gene expression, and aggressive infiltration patterns, demonstrating ASM as a valuable platform for ...

Packed for Ossification: High‐Density Bioprinting of hPDC Spheroids in HAMA Toward Endochondral Ossification

Advanced Healthcare Materials, EarlyView.
Human periosteum‐derived cell spheroids bioprinted at high density within a hyaluronic acid matrix promote fusion and hypertrophic cartilage formation in vitro. Early encapsulation enhances spheroid interaction and matrix maturation, generating scalable cartilage templates intended for endochondral bone regeneration.

Responses of temporal retinal growth cones to ephrinA5-coated beads

, 2005
The topographic positioning of retinal axons in the optic tectum is regulated, at least in part, by ephrinA/EphA repulsive interactions. Temporal axons, expressing high levels of EphA receptors, project to the ephrinA5-poor anterior tectum and avoid the ...

New Light on Growth Cone Navigation [PDF]

Developmental Cell, 2015
Growth cones on neuronal process navigate over long distances to their targets in the developing nervous system. New work by Menon et al., 2015 in the current issue of Developmental Cell reveals that reversible ubiquitination of the actin filament polymerase called VASP is part of the guidance system.

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

Advanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...
