<DIV>From <A
href="http://www.sciscoop.com/story/2003/11/29/4520/0469">SciScoop</A>, more
coverage of the new medical technology developed by the UK company <A
href="http://www.tristemcorp.com/">TriStem</A>: a process to convert
easily-isolated white blood cells into stem cells which it can further culture
to replace any defective tissue in the body. Current scientific dogma holds that
once a stem cell has differentiated into mature body tissue like a blood cell,
the transformation cannot be reversed. TriStem says it can. If true, not only
has TriStem bypassed the current need to obtain stem cells from human embryos
for research; it has revolutionized the very foundation of medicine. This could
transform the treatment of everything from heart disease to Parkinson. <BR>To
say that other scientists have been sceptical of TriStem's claims is an
understatement. "I would be extremely sceptical of these findings and would need
more proof," says stem cell expert Evan Snyder of the Burnham Institute in La
Jolla, California. And yet, TriStem has apparently taken white blood cells of
lab mice, converted them back into stem cells, further treated the stem cells to
make them into blood-producing bone marrow cells, and injected the new bone
marrow cells into the bones of the mice, where the cells took up the duty of
making blood. All of this research effort was performed under the watchful eye
of a third-party U.S. research laboratory team.</DIV></BODY></HTML>
