                        TOKYO (AFP) - 
The monthly discomfort many women see as a curse could pay off someday as Japanese researchers say menstrual blood can be used to repair heart damage.                        
                        </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/afp/20080424/hl_afp/sciencehealthjapanstemcellswomen">
Scientists obtained menstrual blood from nine women and cultivated it for about a month, focusing on a kind of cell that can act like stem cells.</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/afp/20080424/hl_afp/sciencehealthjapanstemcellswomen">
Some 20 percent of the cells began beating spontaneously about three days after being put together in vitro with cells from the hearts of rats. The cells from menstrual blood eventually formed sheet-like <SPAN id="lw_1209025302_0" class="yshortcuts">heart-muscle tissue</SPAN>.</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/afp/20080424/hl_afp/sciencehealthjapanstemcellswomen">
The success rate is 100 times higher than the 0.2-0.3 percent for stem cells taken from <SPAN id="lw_1209025302_1" class="yshortcuts">human bone marrow</SPAN>, according to Shunichiro Miyoshi, a cardiologist at <SPAN id="lw_1209025302_2" class="yshortcuts">Keio University</SPAN>'s school of medicine, who is involved in the research.</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/afp/20080424/hl_afp/sciencehealthjapanstemcellswomen"><P>
Separate in-vivo experiments showed that the condition of rats who had suffered heart attacks improved after they received the cells derived from menstrual blood.</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/afp/20080424/hl_afp/sciencehealthjapanstemcellswomen">
