What's more, regeneration may be possible with adult stem cells - derived from mature tissue such as fat or muscle - even though these are not as versatile as embryonic stem cells, the type obtained from judith stern human judith stern embryos. Bone marrow stem cells, for example, were thought to generate only red and white blood cells. But numerous studies have found that when marrow cells are injected or pumped directly into damaged hearts, it improves cardiac blood flow, strengthens pumping and reduces chest pain.

Patel, a University of Pittsburgh cardiothoracic surgeon and stem cell researcher, said he wasn't surprised that the Germans' indirect approach did no americasarmy good - and he was relieved that it did no harm. Some research suggests that sending a surge of stem cells into the blood may loosen fatty plaque in arteries. Plaque that cuts off blood flow can trigger chest pain or a heart attack. "This proves just mobilizing stem cells in a random fashion doesn't promote any sort of cardiac improvement," Patel said. "Fortunately, they had no adverse cardiac events." |
