SHOWS UMBILICAL CORD MATRIX NEW RICH SOURCE OF STEM CELLS
MANHATTAN, Kan., January 17, 2003 (LifeSiteNews.com) - The cushioning material
or matrix within the umbilical cord known as Wharton's jelly is a rich and
readily available source of primitive stem cells, according to findings by a
research team at Kansas State University. The cells -- called cord matrix stem
cells to distinguish them from cord blood cells -- can be obtained in a
non-invasive manner from an abundant source of tissue that is typically
discarded.
According to researchers Mark Weiss and Deryl Troyer, "Umbilical cord
matrix cells could provide the scientific and medical research community with a
non-controversial and easily attainable source of stem cells for developing
treatments for Parkinson's disease, stroke, spinal cord injuries, cancers and
other conditions."
Among the findings: Wharton's jelly cells from pigs were propagated in the lab
for more than a year without losing potency; they can be stored cryogenically
and engineered to express foreign proteins.
The cells exhibit telomerase activity, a key indicator of stem cells, and they
can be induced to form nerve cells, both neurons and glia, that produce a range
of nerve-cell specific traits. Neurons are the nervous system cells that
transmit signals; glial cells support the neurons.
On the basis of the encouraging results with animal tissue, the team broadened
its investigations to human umbilical cord matrix cells with similar exciting
findings -- human umbilical cord matrix cells differentiate into neurons, too.
The findings are published in the current edition of the journal Stem Cells.
