[extropy-chat] More on TriStem<BR><BR></FONT></DIV>
<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></BLOCKQUOTE></BODY></HTML>
