                        WASHINGTON (Reuters) - 
Researchers trying to find ways to transform ordinary skin cells into powerful stem cells said on Sunday they found a shortcut by "sprinkling" a chemical onto the cells.

Adding the chemical allowed the team at the Harvard Stem Cell Institute in Massachusetts to use just two genes to transform ordinary human skin cells into more powerful <SPAN id="lw_1223831571_0" class="yshortcuts">induced pluripotent stem cells</SPAN> or iPS cells.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.yahoo.com/s/nm/20081012/sc_nm/us_stemcells"><P>
"This study demonstrates there's a possibility that instead of using genes and viruses to reprogram cells, one can use chemicals," said Dr. Doug Melton, who directed the study published in the journal Nature Biotechnology.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.yahoo.com/s/nm/20081012/sc_nm/us_stemcells"><P>
Melton said Danwei Huangfu, a postdoctoral researcher in his lab, developed the new method.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://news.yahoo.com/s/nm/20081012/sc_nm/us_stemcells"><P>
"The exciting thing about Danwei's work is you can see for the first time that you could sprinkle chemicals on cells and make stem cells," Melton, a <SPAN id="lw_1223831571_1" class="yshortcuts">Howard Hughes Medical Institute Investigator</SPAN>, said in a statement.</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/3AA190AD-B545-42C2-9E07-6217A4B44E44/blog/" title="blog or email this clip"><img src="http://content7.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
