TOP STORY
Study Provides Vital New Insight into How We Produce New Brain Cells
Scientists have revealed a crucial mechanism that stops stem cells from dividing or specializing when they are in direct contact with blood vessels in the brain, so that they remain in a dormant state. [Press release from Imperial College London discussing online prepublication in Nature Cell Biology] Press Release | Abstract

PUBLICATIONS (Ranked by impact factor of the journal)
Trithorax Maintains the Functional Heterogeneity of Neural Stem Cells through the Transcription Factor Buttonhead
The authors report that Trithorax (Trx) actively maintains the heterogeneity of neural stem cells (neuroblasts) in the developing Drosophila larval brain. trx mutant type II neuroblasts gradually adopt a type I neuroblast functional identity, losing the competence to generate intermediate neural progenitors and directly generating differentiated cells. [eLife] Abstract | Full Article

Microfluidic Control of Axonal Guidance
Scientists report direct evidence of fluid flow influencing axonal migration, producing turning angles of up to 90°. This method of flow-based guidance was successfully used to fasciculate one advancing axon onto another, showcasing the potential of this technique to be used for the formation of in vitro neuronal circuits.

KLF9 Inhibits Glioblastoma Stemness through Global Transcription Repression and Integrin-α6 Inhibition
Investigators established for the first time a genome-wide map of Krüppel-like factor-9 (KLF9)-regulated targets in human glioblastoma stem-like cells, and show that KLF9 functions as a transcriptional repressor and thereby regulates multiple signaling pathways involved in oncogenesis and stem cell regulation. [J Biol Chem]

Caspr4 Interaction with LNX2 Modulates the Proliferation and Neuronal Differentiation of Mouse Neural Progenitor Cells
The authors show an essential role of contactin associated protein 4 (Caspr4) in neural progenitor cells (NPCs). Neuronal differentiation is increased by overexpression of Caspr4, but decreased by knocking-down of Caspr4 in cultured mouse NPCs. [Stem Cells Dev] Abstract

Radiation-Induced Glioblastoma Signaling Cascade Regulates Viability, Apoptosis and Differentiation of Neural Stem Cells (NSC)
Investigators evaluated the effects of irradiated glioblastoma cells on viability, proliferation and differentiation potential of non-irradiated NSC through radiation-induced signaling cascades. [Apoptosis] Abstract

The Autism Spectrum Disorders Stem Cell Resource at Children’s Hospital of Orange County: Implications for Disease Modeling and Drug Discovery
The authors show that both normal and autism spectrum disorder-specific induced pluripotent stem cells can be differentiated toward a neural stem cell phenotype and terminally differentiated into action-potential firing neurons and glia. [Stem Cells Transl Med] Abstract

Adult Limbal Neurosphere Cells: A Potential Autologous Cell Resource for Retinal Cell Generation
Scientists investigated whether mouse and human limbal neurosphere cells could differentiate towards a retinal lineage both in vivo and in vitro following exposure to a developing retinal microenvironment. [PLoS One]

Inhibition of Na+/K+-ATPase Induces Hybrid Cell Death and Enhanced Sensitivity to Chemotherapy in Human Glioblastoma Cells
Researchers tested the hypothesis that inhibition of Na+/K+-ATPase causes a mixed or hybrid form of concurrent apoptosis and necrosis and should therefore enhance anti-cancer effects of chemotherapy on glioblastoma cells. [BMC Cancer] Full Article

Visualization and Correction of Automated Segmentation, Tracking and Lineaging from 5-D Stem Cell Image Sequences
Investigators present an application that integrates visualization and quantitative analysis of 5-D (x, y, z, t, channel) and large montage confocal fluorescence microscopy images. The image sequences show stem cells together with blood vessels, enabling quantification of the dynamic behaviors of stem cells in relation to their vascular niche, with applications in developmental and cancer biology.

REVIEWS
The Complex Relationships between Microglia, Alpha-Synuclein, and LRRK2 in Parkinson’s Disease
The authors focus on how Parkinson’s disease-associated mutations in LRRK2 could potentially alter microglial biology with respect to neuronally-secreted alpha-synuclein, resulting in cell dysfunction and neurodegeneration. [Neuroscience] Abstract

The Nobel Assembly at Karolinska Institutet has decided to award the 2014 Nobel Prize in Physiology or Medicine with one half to John O´Keefe and the other half jointly to May-Britt Moser and Edvard I. Moser for their discoveries of cells that constitute a positioning system in the brain. [Nobel Media AB] Press Release

Brains in the Balance: New $11.5 Million Grant Fuels U-M Parkinson’s Disease Research Center to Aid Patients
University of Michigan scientists and doctors have launched a five-year, $11.5 million effort to better understand the cause of changes to brain cells that put Parkinson’s disease patients at high risk of dangerous falls, and find new options based in the latest brain science. [University of Michigan] Press Release

Brain Boost: Harvard Researchers among the First to Receive Grant Funding through BRAIN Initiative
