Stem cells are often referred to
as the building blocks of the blood as well as of other
tissues and organs in the body. These stem cells are
very special compared to other cells because they have
the ability to adapt. Unlike other cells within the
body they are non-specific, and this means that they
can ensure the reproduction and healthy growth of cells
in all parts of the body rather than just in a
particular area of the body.
Red blood cells (which transport
oxygen and carbon dioxide around the body and to other
organs and tissue), white blood cells (instrumental in
fighting disease and maintaining the immune system),
and platelets (vital to help the blood to clot) are all
produced from stem cells, so as you can see the stem
cell is indeed a vital requirement for healthy blood
and body.
Most cells within the body are
specific to a particular area such as the heart or the
kidney. However, stem cells are able to ‘fit in’
with other cells, adapting to suit the needs of the
body. In addition to umbilical cord blood, which is
rich in young and valuable stem cells, these calls are
found in the bone marrow and in the blood circulating
around the body.
The other unique thing about stem
cells is that they are able to renew and replicate
themselves for long periods of time by dividing. This
is known as proliferation, and stem cells can
proliferate many times over. The cells produced through
this proliferation can remain as stem cells or can join
the cells of the kidney, liver, heart or any other
tissue or organ of the body.
The discovery that the umbilical cord blood is rich in
stem cells has provided medical experts with a valuable
resource that could lead the way forward in the future
of medical treatment. It is thought that in the future
cord blood stem cells could be used not only to
regenerate blood cells following operations and
transplants but to treat diseases such as diabetes,
heart disease, Alzheimer’s and many others.
