Summary:
Harvard University researchers have discovered that a "master" embryonic cardiac stem cell is able to produce all three types of cardiac tissue. In experiments using mice, the team was able to produce cardiac muscle, smooth muscle and "pacemaker" cardiac cells. According to experts, the findings, outlined in two reports published online Nov. 22 in the journal Cell, could enable doctors to repair hearts by growing new heart cells from embryonic stem cells, specialized cells that have can become any type of cell.
