Researchers at German Research Centre for Environmental Health have revealed that new nerve cells originate from neural stem cells after a brain injury.
Glial cells are supporting cells that serve as a framework for nerve cells and play an important role in the wound reaction that occurs with injuries to the brain.
Nerve cells are electrically excitable cells in the nervous system that process and transmit information and are the core components of the brain and spinal cord.
The study led by Prof. Dr. Magdalena Gotz was conducted using a mouse model where they demonstrated that after injury, these reactive glial cells in the brains restart their cell division.
They then become stem cells from which nerve cells can form yet again under favourable cell culture conditions.
The researchers said that the adult neural stem cells can serve as a source of new nerve cells.
Earlier studies by Gotz showed that glial brain cells can act as stem cells, and nerve cells emerge from glial cells.
"Now, thanks to these results, the distant goal of being able to use the processes therapeutically is getting a little closer," she said.
