Technique Uses Patient’s Own Stem Cells to Repair Brain Damage
Researchers in England are
working on a technique that will use a patient’s own stem cells
to repair brain damage by building a “biological scaffold” that
the cells can attach to and grow on, according to The
Independent.
The technique would use stem
cells that are already present in the patient’s brain but are
inactive. “We know there are stem cells in the human brain,”
Professor Andrea Brand of the Gurdon Institute at Cambridge
University told The Independent. “If we can reactivate stem
cells that are in the right place at the right time, that would
be ideal.”
They hope to one day build the
scaffolding from “synthetically made biological materials” and
then insert it into a brain in which cells have been killed by a
stroke or other types of brain trauma, according to The
Independent. The inactive stem cells would then multiply in the
scaffold and regrow tissue that had been lost.
“We know that stem cells will
sometimes go to sleep and we’re studying ways of reactivating
them,” Brand told The Independent. “This is really key because
what we’d like to do eventually in terms of repairing the brain
is to reactivate someone’s own stem cells in situ to give rise,
hopefully, to the neurons that will replace those that have been
damaged.”
The idea is in the very early
stages of development. The researchers are currently working to
identify genes that are needed to activate the stem cells,
studying simpler nervous systems of creatures such as fruit
flies to learn more about the process.
“In particular, we are interested
in how these stem cells can generate all the different types of
nerve cells that you find in the human brain,” Brand added. |
