Researchers are reporting a key advance in using stem cells to repair hearts damaged by heart attacks. In a study, stem cells donated by strangers proved as safe and effective as patients' own cells for helping restore heart tissue.
"You could have the cells ready to go in the blood bank so when the patient comes in for a therapy _ there's no delay," Hare said. "It's also cheaper to make the donor cells,"
Unlike other cells, these lack a key feature on their surface that makes the immune system see them as foreign tissue and attack them, explained the study's leader, Dr. Joshua Hare of the University of Miami.
