Injection of human umbilical cord blood helps aging brain (3/12/2008)

When human umbilical cord blood cells were injected into aged laboratory animals, researchers found improvements in the microenvironment of the hippocampus region of the animals' brains and a subsequent rejuvenation of neural stem/progenitor cells. ...> Full Article

Stem cell funding for Parkinson's Disease (3/8/2008)

Building Brains: Mammalian-like Neurogenesis In Fruit Flies (3/2/2008)

The nerve cells in the brain of Drosophila are generated by neural stem cell-like progenitor cells called neuroblasts. In the currently accepted model of neurogenesis, these neuroblast divide asymmetrically both to self renew and to produce a smaller progenitor cell. This smaller cell then divides only once into two daughter cells, which receive cell fate determinants, causing them to exit the cell cycle and differentiate into postmitotic neural cells. ...> Full Article

Stem cells helped repair stroke damage in rats, early study shows (2/21/2008)

Neural cells derived from human embryonic stem cells helped repair stroke-related damage in the brains of rats and led to improvements in their physical abilities after a stroke, according to a new study by researchers at the Stanford University School of Medicine. ...> Full Article

Brain Stem Cells Sensitive to Space Radiation (12/12/2007)

Scientists recently led a team of researchers to study potential effects of space radiation on astronauts. The results of their study are revealing and will provide the foundation for ensuring the safety of crew members participating in long distance space travel. Measures to protect astronauts from health risks caused by space radiation will be important during extended missions to the moon or Mars, say researchers in a paper currently online in Experimental Neurology. ...> Full Article

Imaging Neural Progenitor Cells In The Living Human Brain (11/18/2007)

For the first time, investigators have identified a way to detect neural progenitor cells (NPCs), which can develop into neurons and other nervous system cells, in the living human brain using a type of imaging called magnetic resonance spectroscopy (MRS). The finding may lead to improved diagnosis and treatment for depression, Parkinson's disease, brain tumors, and a host of other disorders. ...> Full Article

Team of Scientists Develops Non-Invasive Method to Track Nerve-Cell Development in Live Human Brain (11/10/2007)

A team of scientists have identified and validated the first biomarker that permits neural stem and progenitor cells (NPCs) 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. ...> Full Article

One step closer to transplanting stem cells in the brain (8/22/2007)

Stem cells transplanted into the brains of mice generate more numerous and more mature nerve cells if the brain cells called astrocytes are not activated. This discovery at the Sahlgrenska Academy is an important step forward for stem cell research. ...> Full Article

Scientists Restore Memory In Mice With Neurodegeneration (4/30/2007)

Mice whose brains had lost a large number of neurons due to neurodegeneration regained long-term memories and the ability to learn after their surroundings were enriched with toys and other sensory stimuli, according to new studies by Howard Hughes Medical Institute researchers. The scientists were able to achieve the same results when they treated the mice with a specific type of drug that encourages neuronal growth. ...> Full Article
