Cell-Seeded Sutures to Repair the Heart

Over the last decade, scientists have experimented with using stem cells to heal or replace the scarred tissue that mars the heart after a heart attack. While the cells do spur some level of repair in animals, human tests have resulted in modest or transient benefits at best. Now researchers have developed a new kind of biological sutures, made from polymer strands infused with stem cells, that might help surmount two major obstacles to using stem cells to heal the heart: getting the cells to the right spot and keeping them there long enough to trigger healing.
