That’s still a ways off. But starting with mouse embryonic <A href="http://www.scientificamerican.com/topic.cfm?id=stem-cell-research">stem cells</A>, researchers have succeeded in creating heart muscle that actually beats. The study appears in the October 16th issue of the journal <EM>Science</EM>.</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://www.scientificamerican.com/podcast/episode.cfm?id=beating-heart-tissue-from-stem-cell-09-10-15"> To make beating heart muscle, researchers needed to figure out just which cells were the ones that they needed. They used colored fluorescent tags to identify the groups in question in embryos, allowing the correct cells to be harvested.</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://www.scientificamerican.com/podcast/episode.cfm?id=beating-heart-tissue-from-stem-cell-09-10-15">the researchers borrowed from microchip technology. They created patterns on a film, much like the design for a computer chip. Laying down the cells within these patterns forces them to take the distinctive shape of cardiac muscle cells, which lets the cells link and beat in sync. The ultimate goal is to grow beating heart muscle from a patient’s own cells. And thereby literally mend a broken heart.</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/7E981270-EA25-4BC4-BD1B-DC26E8B09E3A/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>
