Movement of new cells pave way for brain research

---

Omschrijving
Research from The University of Auckland, alongside colleagues in Sweden, has identified how stem cells, immature cells that have not yet developed specific specialised functions, move from the site of generation in the brain, to other areas including those affected by neurological diseases. “We’ve known about the migration of brain cells in mammals for some years but humans have usually been deemed different,” says Professor Richard Faull of the University’s Faculty of Medical and Health Sciences. “Our studies show that stem cells migrate long distances through the human brain in order to replace cells that die in the olfactory system. Utilisation of this migration may allow us to direct the stem cells to other brain regions that are affected by brain cell loss. In addition, our study looked at adult brain tissue, which means much of the brain’s ability to regenerate remains active even in older human brains. “This research will change the way in which we can look at diseases where brain cells die, such as Huntington’s Disease, or require repair, such as stroke. By knowing how stem cells move around, we can now look at new ways to regenerate cells and repair damage to the areas of the brain affected by these conditions.”
