The recent study, which raises new questions of how the brain evolves, is published in the current issue of Nature, one of the world's most cited scientific journals. http://medicalxpress.com/news/2011-09-scientists-stem-cell-human-brain.html Medical research Wed, 28 Sep 2011 14:47:59 EST news236440069 The Allen Institute for Brain Science announced today the discovery of a new class of cells in the spinal cord that act like neural stem cells, offering a fresh avenue in the search for therapies to treat spinal cord injury and disease. The published collaborative study, authored by scientists from the University of British Columbia, the Allen Institute for Brain Science and The Montreal Neurological Institute and Hospital at McGill University and titled "Adult Spinal Cord Radial Glia Display a Unique Progenitor Phenotype," appears in the open access journal PLoS One. http://medicalxpress.com/news/2011-09-class-stem-cell-like-cells-possibility.html Medical research Thu, 15 Sep 2011 11:45:24 EST news235305621 When developing babies are growth restricted in the womb, they are typically born with heads that are large relative to their bodies. The growing brain is protected at the expense of other, less critical organs. Now, researchers reporting in the August 5th issue of Cell, a Cell Press publication, unearth new molecular evidence that explains just how the brain is spared. http://medicalxpress.com/news/2011-08-brain-body-starves.html Other Thu, 04 Aug 2011 12:28:07 EST news231679650 New research may help to explain why the location of postnatal neural stem cells in the brain determines the type of new neurons that are generated. The research, published by Cell Press in the July 28 issue of the journal Neuron, demonstrates that a signaling pathway which plays a key role in development also actively regulates the fate of neural stem cells in the adult brain. Manipulation of this signaling pathway redirected the fate of adult stem cells, a finding that may impact the design of future strategies for creating stem cell therapies. http://medicalxpress.com/news/2011-07-site-affects-fate-postnatal-neural.html Medical research Wed, 27 Jul 2011 13:24:34 EST news230991784 Human neural stem cells are capable of helping people regain learning and memory abilities lost due to radiation treatment for brain tumors, a UC Irvine study suggests. http://medicalxpress.com/news/2011-07-stem-cells-cognitive-abilities-impaired.html Cancer Wed, 13 Jul 2011 13:22:02 EST news229782098 Stem cell therapy may restore cognition in patients with brain cancer who experience functional learning and memory loss often associated with radiation treatment, according to a laboratory study published in Cancer Research, a journal of the American Association for Cancer Research. http://medicalxpress.com/news/2011-07-stem-cell-treatment-cognitive-function.html Cancer Wed, 13 Jul 2011 09:57:16 EST news229769810 Researchers at the Salk Institute have been able to genetically incorporate "unnatural" amino acids, such as those emitting green fluorescence, into neural stem cells, which then differentiate into brain neurons with the incandescent "tag" intact. http://medicalxpress.com/news/2011-07-unnatural-chemical-protein-action-brain.html Medical research Thu, 07 Jul 2011 14:31:22 EST news229267864 Researchers have uncovered a new target that could stop the growth of glioblastoma, a deadly form of brain cancer. In the July 8th issue of the journal Cell, a Cell Press publication, a new study identifies an enzyme found in glioma stem cells that allows them to grow and seed tumors. Importantly, normal stem cells, including those in the brain, don't appear to share that same dependency. http://medicalxpress.com/news/2011-07-combat-deadly-brain-cancer-stem.html Cancer Thu, 07 Jul 2011 12:54:02 EST news229262008 In a study that increases the understanding of the link between fetal development and obesity later in life, researchers at Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) found altering the levels of two common hormones, insulin and leptin, in utero changes the cellular development in the region of the brain that regulates appetite. http://medicalxpress.com/news/2011-06-link-birth-weights-obesity-life.html Health Tue, 21 Jun 2011 09:32:21 EST news227867531 (PhysOrg.com) -- Fear burns memories into our brain, and new research by University of California, Berkeley, neuroscientists explains how. http://medicalxpress.com/news/2011-06-boosts-young-immature-brain-cells.html Psychology & Psychiatry Tue, 14 Jun 2011 12:26:11 EST news227273147 Scientists have known for years that neurogenesis takes place throughout adulthood in the hippocampus of the mammalian brain. Now Columbia researchers have found that under stressful conditions, neural stem cells in the adult hippocampus can produce not only neurons, but also new stem cells. The brain stockpiles the neural stem cells, which later may produce neurons when conditions become favorable. This response to environmental conditions represents a novel form of brain plasticity. The findings were published online in Neuron on June 9, 2011. http://medicalxpress.com/news/2011-06-brain-environmental.html Neuroscience Mon, 13 Jun 2011 13:11:14 EST news227188831 A new article published by Cell Press in the May 26 issue of the journal Neuron provides comprehensive insight into the current status of neural stem cell research and the sometimes labyrinthine pathways leading to stem cell-based therapies. The perspective on translating neural stem cell research into clinical therapeutics is part of a special issue of Neuron devoted to neural stem cells and neurogenesis and is published in collaboration with the May issue of Cell Stem Cell, which also has a selection of reviews on this topic. http://medicalxpress.com/news/2011-05-stem-cell-therapies.html Medical research Wed, 25 May 2011 12:34:08 EST news225545632 German researchers succeed in obtaining brain and spinal cord cells from stem cells of the peripheral nervous system. http://medicalxpress.com/news/2011-05-neural-stem-cells.html Neuroscience Thu, 12 May 2011 11:19:23 EST news224417912
