That would mean human stem cells, which can be grown in great quantities.
Neupogen helps the body build infection-fighting white blood cells, which can be depleted by radiation.
Anti-abortion forces say the research should be confined to adult stem cells, which can be harvested without destroying what they consider embryonic life.
But the segments of the genome also exist in physical form, in the bellies of bacterial and yeast cells, which can be manipulated.
Dr. Johe said such cells, which can be grown in test tubes, might one day be implanted into the brain to rewire broken circuits.
Other regions of the lateral ventricles contain dormant stem cells, which can be activated following brain injury to produce new cells that migrate to the injury site.
One project will use so-called induced pluripotent stem cells, which can be made from a patient's own skin cells and have many of the properties of embryonic stem cells.
This has caused considerable concern because scientists take DNA from tissue of individuals with genetic conditions, insert this into a human or animal egg cell and then create stem cells, which can be grown in laboratories.
Is there a link between telomere length and stress? A. In my lab, we're finding that psychological stress actually ages cells, which can be seen when you measure the wearing down of the tips of the chromosomes, those telomeres.
Both firms are betting on "thin film" solar cells, which can be made with vastly less semiconductor material than traditional silicon-based devices.
Here, we describe a strategy to produce modified endothelial cells, which can be efficiently magnetically guided.
