Growth cone dynamics during the migration of an identified commissural growth cone [PDF]

open access: yesThe Journal of Neuroscience, 1993
We have used time-lapse video microscopy to study the behavior of a neuron, Q1, that pioneers the posterior commissure of the embryonic grasshopper. Our goal is to use time-lapse video as a tool to acquire a precise picture of normal development over time, and thereby identify stereotypic activities that might indicate important interactions necessary ...

FLIM FRET Visualization of Cdc42 Activation by Netrin-1 in Embryonic Spinal Commissural Neuron Growth Cones. [PDF]

open access: yesPLoS ONE, 2016
Netrin-1 is an essential extracellular chemoattractant that signals through its receptor DCC to guide commissural axon extension in the embryonic spinal cord.

Inositol 1,4,5-Trisphosphate Receptor Type 3 Regulates Neuronal Growth Cone Sensitivity to Guidance Signals

open access: yesiScience, 2020
Summary: During neurodevelopment, the growth cone deciphers directional information from extracellular guidance cues presented as shallow concentration gradients via signal amplification.

Non-muscle myosin II regulates neuronal actin dynamics by interacting with guanine nucleotide exchange factors. [PDF]

open access: yesPLoS ONE, 2014
Non-muscle myosin II (NM II) regulates a wide range of cellular functions, including neuronal differentiation, which requires precise spatio-temporal activation of Rho GTPases.

An Emerging Role of PRRT2 in Regulating Growth Cone Morphology

open access: yesCells, 2021
Mutations in the PRRT2 gene are the main cause for a group of paroxysmal neurological diseases including paroxysmal kinesigenic dyskinesia, episodic ataxia, benign familial infantile seizures, and hemiplegic migraine. In the mature central nervous system,

Reproductive effort assessment for woody plants using Siberian spruce and Siberian fir [PDF]

open access: yesE3S Web of Conferences, 2023
The correlation between the yield of Siberian spruce (Picea obovata Ledeb.) and Siberian fir (Abies sibirica Ledeb.) cones and radial wood increments was examined using long-term data (47 years) from direct observations.

Increase in Growth Cone Size Correlates with Decrease in Neurite Growth Rate

open access: yesNeural Plasticity, 2016
Several important discoveries in growth cone cell biology were made possible by the use of growth cones derived from cultured Aplysia bag cell neurons, including the characterization of the organization and dynamics of the cytoskeleton.

A Method to Culture GABAergic Interneurons Derived from the Medial Ganglionic Eminence

open access: yesFrontiers in Cellular Neuroscience, 2018
Understanding the mechanisms guiding interneuron development is a central aspect of the current research on cortical/hippocampal interneurons, which is highly relevant to brain function and pathology.

Growth Factors as Axon Guidance Molecules: Lessons From in vitro Studies

open access: yesFrontiers in Neuroscience, 2021
Growth cones at the tips of extending axons navigate through developing organisms by probing extracellular cues, which guide them through intermediate steps and onto final synaptic target sites.
