Coordination of Progenitor Specification and Growth in Mouse and Chick Spinal Cord
Development requires tissue growth as well as cell diversification. To address how these processes are coordinated, scientists analyzed the development of molecularly distinct domains of neural progenitors in the mouse and chick neural tube. [Science] Abstract | Press Release
Webinar: Brent Reynolds on Identification and Characterization of Neural Stem Cells

Neuregulin 1 Signaling Modulates mGluR1 Function in Mesencephalic Dopaminergic Neurons
An endogenous neuregulin 1/ErbB tone is necessary to maintain metabotropic glutamate receptor 1 (mGluR1) function, by preserving its surface membrane expression in dopaminergic neurons. Consequently, it enables striatal mGluR1-induced dopamine outflow in in vivo conditions. [Mol Psychiatr] Abstract

Blm-s, a BH3-Only Protein Enriched in Postmitotic Immature Neurons, Is Transcriptionally Upregulated by p53 during DNA Damage
Researchers identified a Bcl-2 family gene, Blm-s (Bcl-2-like molecule, short form), enriched in postmitotic neurons of the developing cerebral cortex. BLM-s functions as a BH3-only apoptosis sensitizer/derepressor and causes BAX-dependent mitochondria-mediated apoptosis by selectively binding to prosurvival BCL-2 or MCL-1.

Mouse Embryonic Stem Cell-Derived Cells Reveal Niches that Support Neuronal Differentiation in the Adult Rat Brain
To identify microenvironments in the postnatal and adult rat brain with the capacity to support neuronal differentiation, researchers transplanted dissociated embryoid body (EB) cells to conventional neurogenic and non-neurogenic regions. Their results show a neuronal differentiation pattern of EB cells that was dependent on the host region. [Stem Cells] Abstract

Tenascin-R Promotes Assembly of the Extracellular Matrix of Perineuronal Nets via Clustering of Aggrecan
Researchers investigated whether defects are seen in dissociated and organotypic cultures from hippocampus and forebrain of tenascin-R-deficient mice and whether the structure of perineuronal nets could be normalized. [Philos Trans R Soc B-Biol Sci] Abstract

Aromatic-Turmerone Induces Neural Stem Cell Proliferation In Vitro and In Vivo
In vitro, aromatic (ar)-turmerone increased dose-dependently the number of cultured neural stem cells (NSCs), because of an increase in NSC proliferation. In vitro as well as in vivo, ar-turmerone promoted neuronal differentiation of NSCs. [Stem Cell Res Ther] Full Article | Press Release

Combining Enriched Environment, Progesterone, and Embryonic Neural Stem Cell Therapy Improves Recovery Following Brain Injury
Scientists determined if varying combinations of post-injury enriched environments, progesterone therapy, or embryonic neural stem cell transplantation would improve functional outcomes over just a single therapy. [J Neurotrauma] Abstract

Contact-Mediated Inhibition between Oligodendrocyte Progenitor Cells and Motor Exit Point Glia Establishes the Spinal Cord Transition Zone
Researchers observed that prior to myelination, oligodendrocyte progenitor cells (OPCs) extend processes into the periphery via the motor exit point (MEP) and immediately upon contact with spinal motor root glia retract back into the spinal cord. Characterization of the peripheral cell responsible for repelling OPC processes revealed that it was a novel, central nervous system-derived population of glia the authors propose calling MEP glia. [PLoS Biol] Full Article

miR-135b Contributes to the Radioresistance by Targeting GSK3β in Human Glioblastoma Multiforme Cells
Researchers established a radioresistant human glioblastoma multiforme cell line U87R derived from parental U87 and found miR-135b expression was upregulated in U87R cells. miR-135b knockdown reversed radioresistance of U87R cells, and miR-135b overexpression enhanced radioresistance of U87 cells. [PLoS One] Full Article

Cyclin D1 Acts as a Barrier to Pluripotent Reprogramming by Promoting Neural Progenitor Fate Commitment
Investigators identified Cyclin D1 to be capable of transcriptionally upregulating Pax6, which promoted reprogramming cells to commit to a neural progenitor fate rather than a pluripotent cell fate. [FEBS Lett] Abstract

SPOT14-Positive Neural Stem/Progenitor Cells in the Hippocampus Respond Dynamically to Neurogenic Regulators
Scientists show that aging is accompanied by a marked disappearance of SPOT14+ neural stem/progenitor cells (NSPCs), whereas running, a positive neurogenic stimulus, increases proliferation of SPOT14+ NSPCs. [Stem Cell Rep] Full Article | Graphical Abstract

Immunomodulation in Stem Cell Differentiation into Neurons and Brain Repair
The authors review immunophenotypic expression patterns of different stem cell types, including embryonic stem cell, neural and tissue-specific mesenchymal stem cells, and focus on immunodulatory properties of these cells. [Stem Cell Rev] Abstract

The Future of Glioblastoma Therapy: Synergism of Standard of Care and Immunotherapy
The authors review current glioblastoma therapy and the evidence for combination of immune checkpoint inhibitors, dendritic cell and peptide vaccines with the current standard of care. [Cancers] Full Article
