ONLINE COVER A Broken Heart, Mended. Shown is an injured guinea pig heart successfully repaired with a living patch of tissue grown from human stem cells (Weinberger et al.). The patch contained stem cell–derived blood vessel and heart cells, which caused remuscularization of the injured area and improved pumping of the heart.
