What Is A Cord
Blood Stem Cell
Cord blood, also
called placental blood, is the blood that remains in the
placenta and umbilical cord following the birth of a child,
after the umbilical cord is cut.
In most cases, this blood is disposed of with the placenta
and umbilical cord along with what is called a
cord blood stem
cell. There is much controversy regarding the
use of stem cell research as it pertains to the use of
embryos. However, there have been new scientific
breakthroughs in the field of cord blood stem cell research
from living babies.
To investigate the usefulness in diabetes patients, team of
South Korean researchers, has successfully grown pancreatic
beta cells from umbilical cord blood stem cells of newborn
babies. A cord blood stem cell is able to secrete insulin, the
hormone necessary for treatment of diabetes.
The ability of a cord blood stem cell to differentiate, or
change into other types of cells in the body is a relatively
new discovery that holds great promise for improving the
treatment of some of the most common diseases including
diabetes. Similar breakthroughs have been achieved by
scientists throughout the world.
Researchers in Dublin produced a ‘mini liver’ from
cord blood stem
cells. The technique will be developed to create a
full-sized, fully functioning liver. Tissues from mini-livers
will be used to test new drugs. Researchers are hopeful that
within five years, pieces of the tissue can be used to repair
damaged livers and within 15 years, actual liver transplants
may be done using lab-grown livers made with help from a cord
blood stem cell.
According to a senior investigator of the study, there is
another major discovery that is crucial to understanding how a
cord blood stem cell can restore brain function after injury
such as in stroke. In a laboratory test, cord blood stem cells
were transplanted into rodents who were induced with controlled
strokes. The results: some limb function was restored and the
sizes of brain lesions were reduced. The cord blood stem cell
had developed into neuron-type cells, similar to those found in
the brain.
Cord blood stem cell technology has been
leaping forward. The breakthroughs in cord blood stem cell
research can substantially speed up the development of
treatments for life-threatening diseases and debilitating
conditions. As well, cord blood stem cell research avoids much
of the controversy and problems associated with embryonic stem
cell research.
