Bioengineers and surgeons from Rice University and Baylor College of Medicine (BCM) have shown that shielding stem cells with a novel biomaterial improves the cells' ability to heal heart injuries caused by heart attacks. In a study using rodents, a team led by Rice's Omid Veiseh and Baylor's Ravi Ghanta showed it could make capsules of wound-healing mesenchymal stem cells (MSCs) and implant them next to wounded hearts using minimally invasive techniques. Within four weeks, heart healing was 2.5 times greater in animals treated with shielded stem cells than those treated with nonshielded stem cells, the researchers found.
