Interesting discovery. It's nice that scientists keep discovering new ways that our brains repair and regenerate themselves during adulthood.



Brain creates 'new' nerve cells

Researchers have discovered a type of brain cell that continuously regenerates in humans.

A pool of "resting cells" migrate to create new nerve cells in the part of the brain which deals with smell.

The system has been shown in mice and rats but it was believed it did not exist ...

Biomed firm commercialises stem-cell sales

A U.S. biomedical company said Thursday it reached an agreement to commercialise the distribution of neural stem cells by the billions.
'We`re going to be able to distribute a cell that has the ability to produce all the different cell types in the nervous system,' Aruna Biomedical Inc. Chief Executive Steven Stice told the Atlanta Journal-Constitution.

Stice developed neural progenitor cell technology at the University of Georgia, where he ...

Stem Cells Cultured From Human Bone Marrow Behave Like Those Derived From Brain Tissue

Stem cells taken from adult human bone marrow have been manipulated by scientists at the Maxine Dunitz Neurosurgical Institute at Cedars-Sinai Medical Center to generate aggregates of cells called spheres that are similar to those derived from neural stem cells of the brain.
In addition, the bone marrow-derived stem cells, which could be differentiated into neurons and other cells making ...

This is encouraging.



Neural stem cells lend the brain a surprising capacity for self-repair

The brain contains stem cells with a surprising capacity for repair, researchers report in recent issue of the journal Cell. 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.

The researchers found that mice whose brains were severely damaged by loss of the genes “Numb” ...

Interesting research...



New study supports a stem cell origin of cancer

Researchers at the University of Southern California (USC) recently made significant strides toward settling a decades-old debate centering on the role played by stem cells in cancer development.

According to the study's findings, which appear in an upcoming issue of Nature Genetics and now available online, genes that are reversibly repressed in embryonic stem cells are over-represented among genes that are permanently silenced in ...
