TOP STORY


Stem Cells Become Functioning Neurons in Mice
Transplanted neurons grown from embryonic stem cells were able to form proper brain connections in newborn mice, according to researchers. [Stanford Medical School, Stanford]

SCIENCE NEWS


Discovery of a New Molecular Mechanism that Guides Visual Nerves Towards the Brain
Using genetic evidence and in utero manipulations in mice, researchers were able to demonstrate that the Sonic Hedgehog molecular pathway is required for the guidance of retinal axons within the optic chiasm. [Institut de recherches cliniques de Montreal, Montreal]


‘Noisiest’ Neurons Persist in the Adult Brain, Research Finds
The observation that the “noisiest” neurons have a survival advantage helps explain the prevalence of epilepsy, in which some neurons become hyperactive and fire in an uncontrollable fashion. [Massachusetts Institute of Technology, Cambridge]


New Stroke Therapy Successful in Rats
People with impaired mobility after a stroke soon may have a therapy that restores limb function long after the injury, if a supplemental protein works as well in humans as it does in paralyzed rats. [University of California, Irvine]


Cancer Stem Cells Suppress Immune Response Against Brain Tumor
The researchers demonstrate that cancer-initiating cells that launch glioblastoma multiforme, stifles the immune response in a variety of ways, but that the effect can be greatly diminished by encouraging the stem cells to differentiate into other types of brain cell. [University of Texas M.D. Anderson Cancer Center, Houston]

CURRENT PUBLICATIONS


Subventricular Zone-Derived Neural Progenitor Cells Migrate Along a Blood Vessel Scaffold Toward the Post-Stroke Striatum
Findings suggest that blood vessels play an important role as a scaffold for neural progenitor cells migration toward the damaged brain region. [Stem Cells]


Regulation of Neural Crest Cell Fate by the Retinoic Acid and Pparg Signalling Pathways
As in other vertebrates, zebrafish osteoblasts and adipocytes were shown to originate in part from cephalic neural crest precursors. [Development]


A Protein Interaction Network for the Analysis of the Neuronal Differentiation of Neural Stem Cells in Response to Titanium Dioxide Nanoparticles
Titanium dioxide (TiO2) nanoparticles (NPs) lead to a differentiational tendency towards neurons from neural stem cells, suggesting TiO2 NPs might be a beneficial inducer for neuronal differentiation. [Biomaterials]


Human Neural Stem Cell Grafts Modify Microglial Response and Enhance Axonal Sprouting in Neonatal Hypoxic-Ischemic Brain Injury
The efficacy of human neural stem cells derived from human embryonic stem cells in a rat model of neonatal hypoxic-ischemic and the mechanisms enhancing brain repair  were investigated. [Stroke]


Human Cytomegalovirus Infection Causes Premature and Abnormal Differentiation of Human Neural Progenitor Cells
Research suggests that human cytomegalovirus infection causes in utero central nervous system defects by inducing both premature and abnormal differentiation of neural progenitor cells. [J Virol]


Dual-Specificity Histone Demethylase KIAA1718 (KDM7A) Regulates Neural Differentiation Through FGF4
KIAA1718 was identified as a novel histone demethylase specific for the two repressing marks of dimethylated histone H3 lysine 9 and lysine 27. [Cell Res]


Neural Crest Regionalisation for Enteric Nervous System Formation: Implications for Hirschsprung’s Disease and Stem Cell Therapy
Researchers mathematically modelled a proliferative difference between neural crest populations, with a plexus preference hierarchy, in the context of intestinal growth. [Dev Biol]


Differentiation Factors that Influence Neuronal Markers Expression In Vitro from Human Amniotic Epithelial Cells
The differentiation of neural cells in vitro from amniotic epithelial cells (AEC) following AECs treatment with retinoic acid, basic fibroblast growth factor (bFGF) as well as investigation of bFGF withdrawal on neuronal differentiation was examined. [Eur Cell Mater]


Cyclic GMP Modulates Stem Cells Differentiation to Neurons in Brain In Vivo
The aim of this work was to assess the role of cyclic GMP in the modulation of differentiation of neural stem cells to neurons or non-neuronal cells. [Neuroscience]
