Dec. 2--Researchers reported Wednesday that bone marrow stem cells were unable to regenerate damaged heart tissue in laboratory animals, suggesting that a proposed revolutionary therapy for the 1.1 million Americans who suffer heart attacks each year may be destined to fail.

The study is the latest to cast doubts on the scientific dream that a patient's own mature stem cells -- instead of stem cells from embryos -- could someday be used to replace cells damaged or missing because of genetic diseases, tissue injuries or degenerative illnesses.

Earlier studies had been very optimistic about the capability of bone marrow stem cells to be coaxed into growing new heart cells so that a weakened heart can regain…
