08-07-2007 · EurekAlert!
Scientists with the Institute of Stem Cell Biology and Medicine at UCLA were able to produce from human embryonic stem cells a highly pure, large quantity of functioning neurons that will allow them to create models of and study diseases such as Alzheimer's, Parkinson's, prefrontal dementia and schizophrenia.

- Neural stem cells lend the brain a surprising capacity for self-repair
12-14-2006 · EurekAlert!
The brain contains stem cells with a surprising capacity for repair, researchers report in the Dec. 15 issue of the journal Cell, published by Cell Press. The novel insight into the brain's natural ability to heal might ultimately have clinical implications for the treatment of brain damage, according to the researchers.

- Team of scientists develops non-invasive method to track nerve-cell development in live human brain
11-08-2007 · EurekAlert!
A team of scientists including researchers at Cold Spring Harbor Laboratory have identified and validated the first biomarker that permits neural stem and progenitor cells to be tracked, non-invasively, in the brains of living human subjects. This important advance could lead to significantly better diagnosis and monitoring of brain tumors and a range of serious neurological and psychiatric disorders.

- Neural stem cell study reveals mechanism that may play role in cancer
09-04-2007 · EurekAlert!
In the dynamic world of the developing brain, neural stem cells give rise to neurons deep within the brain’s fluid-filled ventricles. These newborn neurons then migrate along the stem cell fibers up to the neocortex, the seat of higher cognitive functions. Now, scientists have discovered a key mechanism of this migration -- one that may also play an important role in other developmental processes and diseases, including cancer.

- New use for stem cells found in war on terrorism
09-25-2007 · EurekAlert!
For more than a decade, Steve Stice has dedicated his research using embryonic stem cells to improving the lives of people with degenerative diseases and debilitating injuries. His most recent discovery, which produces billions of neural cells from a few stem cells, could now aid in national security. In collaboration with the US Naval Research Laboratory, Stice hopes to use his recently developed neural cell kits to detect chemical threats.

- HIV is a 'double hit' to the brain
08-15-2007 · EurekAlert!
New evidence reported in the August issue of Cell Stem Cell, a publication of Cell Press, offers a novel perspective on how the HIV/AIDS virus leads to learning and memory deficits, a condition known as HIV-associated dementia. A protein found on the surface of the virus not only kills some mature brain cells, as earlier studies had shown, but it also prevents the birth of new brain cells by crippling "adult neural progenitors," the new study finds.

- Parkinson's approach with stem cells a promising first step
12-01-2006 · EurekAlert!
Brain cells derived from human embryonic stem cells improved the condition of rats with Parkinson's-like symptoms dramatically, but the treatment caused a significant problem -- the appearance of brain tumors -- that scientists are now working to solve. The study is featured on the cover of the November issue of Nature Medicine.
