Bioengineers and surgeons from Rice University and Baylor College of Medicine 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 and implant them next to wounded hearts using minimally invasive techniques.
