Researchers explore molecular mechanisms through which lead exposure may affect neural stem cells

Researchers have identified a potential molecular mechanism through which lead, a pervasive environmental toxin, may harm neural stem cells and neurodevelopment in children.

Researchers unravel mechanism by which hippocampal stem cells regulate their own fate

To date, it has been assumed that the differentiation of stem cells depends on the environment they are embedded in.

USC researchers discover two Zika proteins potentially responsible for microcephaly

USC researchers have tracked down two Zika proteins potentially responsible for thousands of microcephaly cases in Brazil and elsewhere — taking one small step toward preventing Zika-infected mothers from birthing babies with abnormally small heads.

Scientists use new non-invasive PET scanning method to monitor hippocampal neurogenesis

Scientists from the RIKEN Center for Life Science Technology in Japan have used a new non-invasive PET scanning technique to obtain images of neuron proliferation in the subventricular zone and subgranular zone of the hippocampal dentate gyrus. Neurogenesis in the hippocampal dentate gyrus is known to be particularly affected by depression.

Scientists develop model using transformed stem cells to accelerate screening of drugs for rare cancers

Researchers at the Johns Hopkins Kimmel Cancer Center say they have developed a system that uses transformed human stem cells to speed up screening of existing drugs that might work against rare brain and other cancers.

Choroid plexus signals in the brain control stem cell behavior

Prof. Fiona Doetsch's research team at the Biozentrum, University of Basel, has discovered that the choroid plexus, a largely ignored structure in the brain that produces the cerebrospinal fluid, is an important regulator of adult neural stem cells.

New technique may help replace brain cells, restore memory

Although brains—even adult brains—are far more malleable than we used to think, they are eventually subject to age-related illnesses, like dementia, and loss of cognitive function.

Transplantation of hpNSCs into non-human primates modeled with PD promotes behavioral recovery

A multi-center team of researchers in the U.S. testing the potential of cell therapy for treating Parkinson's disease (PD) has found that grafting human parthenogenetic stem cell-derived neural stem cells (hpNSCs) into non-human primates modeled with PD promoted behavioral recovery, increased dopamine concentrations in the brain, and induced the expression of beneficial genes and pathways when compared to control animals not transplanted with stem cells.

Histone mutation linked to fatal pediatric brain tumor

A single defect in a gene that codes for a histone — a "spool" that wraps idle DNA — is linked to pediatric cancers in a study published today in the journal Science.

Study reveals glioblastoma subtypes tend to develop in different regions of the brain

Researchers at University of California San Diego School of Medicine have demonstrated that distinct types of glioblastoma, the most common form of brain cancer in adults, tend to develop in different regions of the brain. This finding provides an explanation for how the same cancer-causing mutation can give rise to different types of brain malignancies.

Experimental cancer drug Nutlin-3 shows promise in cancelling effects of fragile X syndrome

A University of Wisconsin-Madison researcher who studies the most common genetic intellectual disability has used an experimental drug to reverse — in mice — damage from the mutation that causes the syndrome.

Hippo signaling pathway controls phases of quiescence in fruit fly central nervous system

Neural stem cells are responsible for the formation of differentiated daughter cells in the developing brain. If no new cells are needed, the stem cells may enter a resting phase called quiescence. Biologists at Johannes Gutenberg University Mainz have now discovered that the phases of quiescence in the Drosophila fruit fly central nervous system are controlled by the Hippo signaling pathway. Drosophila serves as a model organism that helps geneticists to decode the molecular fundamentals of cellular biology and unravel mechanisms that are conserved in human beings and other vertebrates.

Researchers reposition existing prazosin drug to combat glioblastoma

Treatments available for glioblastoma—malignant brain tumors—have little effect. An international collaboration led by the Laboratoire Neurosciences Paris-Seine tested active ingredients from existing medications and eventually identified one compound of interest, prazosin, on these tumors. Not only did it seem to be effective in this type of cancer, but it also acted on a signaling pathway that is common with other cancers.

Study shows beneficial effect of hNSC transplantation for TBI

Traumatic brain injury (TBI) is a major cause of mortality and morbidity, often causing lifelong disability for those who survive. Treatment is limited to supportive care, but stem cell therapy has received recent attention as a way to promote recovery for injuries to the central nervous system (CNS). In this study, researchers transplanted human neural stem cells (hNSCs) into the brains of mice modeled with TBI to investigate whether the hosts' immune systems and the stem cells acting in concert would enhance repair.

Researchers successfully use stem cells to promote nerve fibre regeneration after spinal cord injuries

Researchers from Hokkaido University in Japan together with an international team of scientists implanted specialized embryonic stem cells into the severed spinal cords of rats.

Brazilian researchers reveal harmful effects of Zika virus in human neural stem cells, neurospheres

Brazilian researchers from the D'Or Institute for Research and Education (IDOR) and Federal University of Rio de Janeiro (UFRJ) have demonstrated the harmful effects of ZIKA virus (ZIKV) in human neural stem cells, neurospheres and brain organoids.

Stem cell-derived neurons used to regenerate lost tissue in damaged corticospinal tracts of rats

Writing in the March 28, 2016 issue of Nature Medicine, researchers at University of California, San Diego School of Medicine and Veterans Affairs San Diego Healthcare System, with colleagues in Japan and Wisconsin, report that they have successfully directed stem cell-derived neurons to regenerate lost tissue in damaged corticospinal tracts of rats, resulting in functional benefit.

Researchers develop unique approach to track, label neural stem cells

An overwhelming number of researchers still struggle within the black hole of the effectiveness and safety of stem cell therapy for neurological diseases. While the complexity of understanding how neurons grow, connect and function has long been studied, it remains a mystery, one that graduate student Forrest Goodfellow in the University of Georgia Regenerative Bioscience Center is helping unravel.

UW-Madison neuroscientist discover genetic machinery that causes maturation in young nerve cells

In one of the first studies to 'read' the genetic activity inside individual brain cells, University of Wisconsin-Madison neuroscientist Xinyu Zhao has identified the genetic machinery that causes maturation in a young nerve cell. The cells under study came from the hippocampus, a memory-related structure that is the only place in a mammal's brain where new neurons can form throughout life.

Neural stem cells from T cell-derived iPSCs provide neurological disease model

Researchers in Japan report that neural stem cells derived from readily available T cell-derived iPSCs provide a neurological disease model when cultured in a novel protocol developed by them. The findings are important for the treatment of Parkinson’s disease and are published in Stem Cell Reports, March 2016.
