Post Brain Injury: New Nerve Cells Originate From Neural Stem Cells

ScienceDaily (Mar. 16, 2008) — Most cells in the human brain are not nerve cells, but supporting cells (glial cells). They serve as a framework for nerve cells and play an important role in the wound reaction that occurs with injuries to the brain. However, what these 'reactive glial cells' in the brains of mice and men originate from, and which cells they evolve into was unknown until now.

The study group of Prof. Dr. Magdalena Götz is now able to show that after injury, these reactive glial cells in the brains of mice restart their cell division. They then become stem cells from which nerve cells can form yet again under favourable cell culture conditions.
