It has long been thought that cells that regenerate tissue do so by regressing to a developmentally younger state. Now two University of Washington researchers have demonstrated that cells can regenerate without becoming "younger."

A Medical College of Wisconsin research team, led by John W. Lough, Ph.D., professor of cell biology, neurobiology and anatomy has found that embryonic stem cells in animals can be cultivated to form new tissue, which eventually may help doctors learn how to replace tissue damaged as a result of a heart attack.

Once a mere fantasy, the idea of growing new, healthy heart tissue to replace damaged or diseased heart muscle is inching closer to reality. Researchers are exploring several routes to grow new heart muscle, according to the January issue of the Harvard Heart Letter.
