Human stem cells taken from skeletal muscles called myoendothelial cells is able to repair damaged heart muscles in mice. Now the researchers, from Children’s Hospital of Pittsburgh plans to begin clinical trials in humans next month.

The lead researcher of the study said that the cells were 40 to 50 percent more effective at repairing hearts in mice than previous approaches. The difference seems to be that myoendothelia cells block scar tissue, which can cause a second heart attack and defeat the purpose of the stem cell injections.
