Control of microtubule assembly in growth cones

open access: yes, 1991
Growth cones are transient structures present at the tips of growing axons and dendrites (neurites). They are crucial to neuronal development because of their pathfinding ability and their role in synaptogenesis (reviewed by Dodd and Jessell, 1988).

Dynamics of the endoplasmic reticulum and other membranous organelles in growth cones of cultured neurons

open access: yes, 1989
The fluorescent lipophilic dye 3,3′-dihexyloxacarbocyanine iodide [DiOC6(3)] was used to examine the distribution of membrane-bound organelles in growth cones of cultured rat sympathetic neurons.

Ferroelectric Dynamic‐Field‐Driven Nucleation and Growth Model for Predictive Materials‐To‐Circuit Co‐Design

open access: yesAdvanced Materials, EarlyView.
This study presents a compact dynamic‐field‐driven nucleation and growth (DFNG) model that captures ferroelectric switching behavior under arbitrary voltage waveforms. It enables extraction of time‐dependent domain wall velocity and growth dimensionality, which can then be extended to device‐level modeling.

Pathfinding by identified growth cones in the embryonic zebrafish brain.

open access: yes, 1991
The embryonic zebrafish (Brachydanio rerio) brain was studied to explore its potential as a system to investigate mechanisms of growth cone guidance in the early vertebrate brain.

Localized collapsing cues can steer growth cones without inducing their full collapse

open access: yes, 1995
Collapsing factors are proteins that induce growth cone collapse and paralysis when added in a soluble form to cultured embryonic neurons. Here we examine the responses of growth cones to localized collapsing signals.

Soft, Degradable, and Magnetic Microcarriers for Encapsulation and Guided Transport of Drugs and 3D Spheroids

open access: yesAdvanced Materials, EarlyView.
This work presents soft, degradable hydrogel microcarriers that combine magnetic responsiveness with the ability to host multiple therapeutic and cellular components. Produced by droplet microfluidics, the carriers maintain structural integrity during manipulation, permit controlled breakdown under physiological conditions, and enable guided motion for

Optical Properties of Quantum Cones Formed in Semiconductors by Laser Radiation

open access: yes
Nowadays, nanostructures are one of the most investigated objects in semiconductor physics, especially due to Quantum confinement effect in quantum dots (0D), quantum wires (1D) and quantum wells (2D).

Integrin-cytoskeletal interactions in neuronal growth cones

open access: yes, 1995
Development of the nervous system requires that neuronal growth cones, in coordination with growing axons, migrate along precise paths defined by specific extracellular matrix cues until they encounter their targets.
