"The Stem Cell Debate"

"The stem cell debate in N. America and Europe is shrouded in confusion, =
media hype, political spin and biased, ill-informed input from =
self-interested 'celebrities.' The debate centers around embryonic stem =
cells which are promoted as a potential panacea. No mention is ever made =
of any other sources of stem cells in these debates and the Earth =
shattering moral, religious, ethical and legal objections to embryonic =
stem cells are brushed aside as irrelevant to the overall 'good' which =
will come from embryonic stem cell therapies. The subject has even =
become a part of the US Presidential debate!

In the early 1980's Bob Edwards and myself at Cambridge University =
carried out the early experiments on embryonic stem cells using a mouse =
model. We showed that the cells had enormous potential in that they =
repaired radiation damage in mice very readily. Despite these promising =
results in the laboratory we knew that to try to apply such technology =
to the human in the clinic would raise serious objections. The current =
debate highlights these early fears. One major, debate crushing point =
which is consistently ignored is the fact that there is another easily =
accessible, just as promising, source of stem cells. This source is =
umbilical cord blood.

Umbilical cord blood stem cells have been collected and transplanted =
since 1988. Over 3,000 transplants have been carrier out Worldwide for =
over 45 different diseases. These diseases include the leukemia's, =
related blood disorders and repair of the bone marrow following high =
dose chemotherapy for cancer. Umbilical cord blood can be collected at =
the birth of every baby but currently less than 1% of deliveries =
actually collect the cord blood. This life saving source of stem cells =
is being discarded as biological waste on a daily basis at the same time =
as other people argue for the creation of embryonic stem cells. =
Umbilical cord blood stem cells have also been shown to be capable of =
forming every tissue type in the body which is exactly the argument for =
the use of embryonic stem cells. Umbilical cord blood stem cells carry =
just as much, if not more, promise as embryonic stem cells in terms of =
future therapies for a whole range of disease.

The collection of umbilical cord blood stem cells is a quick, painless =
and risk free procedure carried out just after a baby is born. A needle, =
attached to a blood collection bag, is inserted into the umbilical cord =
and blood is allowed to drain into the collection bag. This is then sent =
to the laboratory for processing and freezing in liquid nitrogen. Once =
frozen the sample is stable indefinitely. This process is a cheap and =
easy way of obtaining stem cells which have all the potential of =
embryonic stem cells without the objections.

The stem cell debate is confused. The public is confused. The =
politicians are confused. The hard fact is that we should be =
concentrating all of our time, money and expertise on the development of =
umbilical cord blood stem cell technologies. This is where the current =
and future applications of stem cells truly lie."
