Summary:
In a new study, researchers tested human embryonic stem cells as a way to repair rats' hearts after heart attacks. First, the scientists coaxed human embryonic stem cells in a test tube into becoming heart cells. Next, they mixed those fledgling heart cells with a "cocktail" of chemicals made to help the heart cells stick to the rats' heart tissue. Not all of the stem-cell-derived heart cells survived. But some did, and those heart cells helped strengthen the rats' hearts four weeks after transplantation, the researchers reported.
