University of Maryland Study Suggests Neonatal Cardiac Stem Cells May Help Restore Heart Function


Researchers at the University of Maryland School of Medicine, who are exploring novel ways to treat serious heart problems in children, have conducted the first direct comparison of the regenerative abilities of neonatal and adult-derived human cardiac stem cells. Among their findings: cardiac stem cells (CSCs) from newborns have a three-fold ability to restore heart function to nearly normal levels compared with adult CSCs. Further, in pre-clinical models of heart attack, hearts treated with neonatal stem cells pumped stronger than those given adult cells. The study is published in the September 11, 2012, issue of Circulation.

In this video the study's senior author, Dr. Sunjay Kaushal, M.D., Ph.D., director of pediatric cardiac surgery at the University of Maryland Medical Center, discusses the findings in more detail.
