1. Muscle from bone
A potential treatment for heart failure relies on stem cells from bone marrow to renew the heart's pumping tissue.
2. Cellular injection The bone marrow stem cells are injected via a catheter into the heart either immediately following a heart attack or once the heart has become too weak and stiff to pump properly.
3. New life Results suggest that the bone marrow stem cells can heal damaged tissues, but it is not yet clear whether the stem cells turn into adult heart cells themselves or encourage division and regeneration among existing heart cells. Credit: illustration © 2011 Tolpa Studios, Inc.
