Summary:
US scientists have found the “home” of stem cells in the heart, giving credibility to the idea that the heart has the capacity to repair itself. The finding raises the possibility that these cardiac stem cells could one day be able to regnerate tissues damaged by heart disease.
Scientists have tested this idea by removing tiny numbers of cardiac stem cells from people undergoing heart operations, growing them in the lab and then transplanting them into the damaged hearts of rats and mice. The results may lead to better heart repair than cells taken from bone marrow. Scientists say the primary goal of the experiment is to learn how the cells work.
Commentary: Hopefully this study will give scientists a basis to develop effective clinical treatments for humans with heart tissue damage resulting from a heart attack.
