TOP STORY
Sea Anemones – Masters of Producing New Nerve Cells
Researchers have revealed how a seemingly simple animal is able to produce nerve cells throughout its entire body. They show that the stem cells that a sea anemone uses to generate its nervous system are more similar to those of humans than expected. [Press release from the Uni Research Sars Centre discussing research published in Development] Press Release | Abstract
Efficiently Expand hPSC-Derived NPCs Without Loss of Multipotency: STEMdiff™ Neural Progenitor Medium
 
PUBLICATIONS (Ranked by impact factor of the journal)
A Secretagogin Locus of the Mammalian Hypothalamus Controls Stress Hormone Release
Single-cell transcriptome analysis combined with protein interactome profiling identifies secretagogin neurons as a distinct corticotropin-releasing hormone-releasing neuron population reliant on secretagogin’s Ca2+ sensor properties and protein interactions with the vesicular traffic and exocytosis release machineries to liberate this key hypothalamic releasing hormone. [EMBO J] Abstract | Press Release

Neural Progenitor Cells Orchestrate Microglia Migration and Positioning into the Developing Cortex
Researchers show that the ablation of basal progenitors as well as genetic loss of ​Cxcl12 affect microglia recruitment into the subventricular zone. Ectopic ​Cxcl12 expression or pharmacological blockage of ​CxcR4 further supports that ​Cxcl12/​CxcR4 signaling is involved in microglial recruitment during cortical development. [Nat Commun] Abstract

A Competitive Advantage by Neonatally Engrafted Human Glial Progenitors Yields Mice Whose Brains Are Chimeric for Human Glia
Scientists found that in human glial progenitor cells-xenografted mice, the human donor cells continue to expand throughout the forebrain, systematically replacing the host murine glia. [J Neurosci] Abstract

TRPM2 Channel Deficiency Prevents Delayed Cytosolic Zn2+ Accumulation and CA1 Pyramidal Neuronal Death after Transient Global Ischemia
Researchers investigated the role of ROS-sensitive transient receptor potential melastatin-related 2 (TRPM2) channel. Using in vivo and in vitro models of ischemia-reperfusion, they showed that genetic knockout of TRPM2 strongly prohibited the delayed increase in the cytosolic Zn2+ level , ROS generation, CA1 pyramidal neuronal death and postischemic memory impairment. [Cell Death Dis] Full Article | Press Release

Nurr1 Blocks the Mitogenic Effect of FGF-2 and EGF, Inducing Olfactory Bulb Neural Stem Cells to Adopt Dopaminergic and Dopaminergic-Gabaergic Neuronal Phenotypes
Scientists found that expressing Nurr1 in proliferating olfactory bulb stem cells produces a marked inhibition of cell proliferation and the generation of immature neurons immunoreactive for tyrosine hydroxylase concomitant with marked up-regulations of Th, Dat, Gad and Fgfr2 transcripts. [Dev Neurobiol] Abstract

Stroke Increases Neural Stem Cells and Angiogenesis in the Neurogenic Niche of the Adult Mouse
Stroke substantially increased the number of glial fibrillary acidic protein positive neural stem cells that are in contact with the cerebrospinal fluid via their apical processes at the center of pinwheel structures formed by ependymal cells residing in the lateral ventricle. [PLoS One] Full Article

In Vitro Characteristics of Valproic Acid and All-Trans-Retinoic Acid and Their Combined Use in Promoting Neuronal Differentiation while Suppressing Astrocytic Differentiation in Neural Stem Cells
Researchers compared the time-dependent characteristics of valproic acid and all-trans-retinoic acid in neural stem cell differentiation and neurite outgrowth in vitro and, for the first time, demonstrate the improved efficacy of their combined application in neuronal induction and astrocytic suppression. [Brain Res] Abstract

Gypenosides Protected the Neural Stem Cells in the Subventricular Zone of Neonatal Rats that Were Prenatally Exposed to Ethanol
Scientists tested the effect of prenatal ethanol exposure on the neonatal subventricular zone, and the protection potential of gypenosides on neural stem cells in fetal alcohol spectrum disorder rats. [Int J Mol Sci]

Vitamin E Isomer δ-Tocopherol Enhances the Efficiency of Neural Stem Cell Differentiation via L-Type Calcium Channel
Researchers investigated the effects of δ-tocopherol on neural stem cell (NSC) neural differentiation, maturation and its possible mechanisms. Neonatal rat NSCs were grown in suspended neurosphere cultures, and were identified by their expression of nestin protein and their capacity for self-renewal. [Neurosci Lett] Abstract

REVIEWS
Insulin and IGF Receptor Signaling in Neural-Stem-Cell Homeostasis
The authors discuss emerging data on the functions of insulin-like growth factor (IGF)-II and IGF and/or insulin receptor signaling in the context of neural stem cells (NSC) regulation in the subventricular zone and subgranular zone. They also propose a model for IGF-II in which the choroid plexus is a major component of the NSC niche. [Nat Rev Endocrinol] Abstract
