Summary:
Researchers at Lund University have discovered a new stem cell in the adult brain. These cells can proliferate and form several different cell types - most importantly, they can form new brain cells. Now the researchers hope to put the discovery to use to develop methods that can repair diseases and injury to the brain.
Analysing brain tissue from biopsies, the researchers for the first time found stem cells located around small blood vessels in the brain. The cell’s specific function is still unclear, but its plastic properties suggest great potential. A similar cell type has been identified in several other organs where it can promote regeneration of muscle, bone, cartilage and adipose tissue.
In other organs, researchers have shown clear evidence that these types of cells contribute to repair and wound healing. Scientists suggest that the curative properties may also apply to thebrain. The next step is to try to control and enhance stem cell self-healing properties with the aim of carrying out therapies targeted to a specific area of the brain.
The study, published in the journal PLoS ONE, is of interest to a broad spectrum of brain research. Future possible therapeutic targets range from neurodegenerative diseases to stroke.
